How many countries have hydrogen bombs? and how many have atomic bombs?

I couldn't find the answer to the nuclear vs. thermonuclear part of your question.  Once you can make a nuclear weapon, making a thermonuclear weapon is not that difficult.\n\nThere are currently five states considered to be "nuclear weapons states", an internationally recognized status conferred by the Nuclear Non-Proliferation Treaty (NPT). In order of acquisition of nuclear weapons these are: the United States of America, Russia (formerly the Soviet Union), the United Kingdom, France, and the People's Republic of China. Since the formulation of the NPT, two non-signatory states of the NPT have conducted nuclear tests—India and Pakistan. North Korea has publicly declared itself to possess nuclear weapons though it has not conducted any confirmed tests and its ultimate status is still unknown. Israel is strongly suspected to have an arsenal of nuclear weapons though it has never confirmed or denied this, and there have been reports that over 100 nuclear weapons might be in its inventory. This status is not formally recognised by international bodies; none of these countries are currently signatories of the Nuclear Non-Proliferation Treaty. There is some speculation that Iran has, or is preparing for, a secret nuclear weapons program. South Africa was once a nuclear weapons state but has since destroyed its former arsenal.\n\nWikipedia knows all.

Anit-matter is related to the atomic bomb? How?  The "atomic" bomb was a device that created a nuclear fission chain reaction.  No anti-matter was used.  The modern "nuclear" or "hydrogen" bombs are fusion devices (which create the energy needed for the fusion reaction by first detonating an atomic fission device), but still, no anti-matter involved.  \nNow, a positron (or the anti-electron) can come about under certain circumstances of a photon interacting with things such as carbon or fluorine and a couple others causing beta particle decay, but none of the right elements was used in any bomb.

There are 193 countries in the world. \n\nhttp://geography.about.com/library/misc/blnationalcapitals.htm\n\nThere are 61 territories and 6 disputed territories.\n\nhttp://www.infoplease.com/ipa/A0762461.html

none, the 2 different bombs you are trying to get at are usually called atomic and hydrogen bombs\n\natomic (that was dropped over Japan 1946) is uncontrolled splitting (fission) of uranium whereas in the nuclear power reactors this is done slowly -- the reaction is controlled.\n\nhydrogen bomb was never tested over human population (only atoll Bikini) is a synthesis (fusion) of hydrogen into helium. This reaction produces the energy from the Sun and it is still in a research mode here on earth to get this reaction under control.\nIt would be much more effective source of energy than the nuclear one.

http://www.fas.org/nuke/guide/israel/nuke/\n\nThis is an estimate of the size of the nuclear program of Israel up to 2000; the text is in the Federation of  American Scientists site. The number in the graph shows something around 200 !\n\nMind you that the text cites that in the Yom Kipur war probably around 13-14 atomic bombs were build. Apparently, none of them were used, since the war was using only conventional weapons.\n\nWe all know that only two atomic bombs were used in history though, both of them in Japan by the american army.

Hydrogen.  To be more specific, the H1 isotope.  The deuterium or H2 atom is only one in eight thousand of all hydrogen atoms.\nThe second most common element, helium, is less than 10%.  All others together are a minor component, no matter how important to us.

atomic bombs and Hydrogen bombs are types of nuclear bombs. in plan atom bombs there is an outer layer of high explosives and an inner layer of unstable isotopes like plutonium or uranium. the unstable isotopes and and their atoms react in fission from the pressure caused by the explosives the atoms burst and particles from that collide and burst other atoms creating a chain reaction. the H bomb uses fusion reaction with Hydrogen were the atoms are fused together due to the reacting high explosives and often isotopes surrounding the hydrogen fusing them into helium and other atoms.\n\nsimply the atom bomb uses fission with isotopes\nand the H bomb uses the fusion of hydrogen to increases the power

Most countries i believe have the technology. Its actually about producing it. I believe our government and the UN have treaties about the amount of nuclear power to have for each countries.

The experts at NRDC estimate between 30-35 (2002 est.) with enough weapons-grade plutonium for 50-90 more nuclear weapons. \nThe website Armgeddon Online claims they have 70.

7 satelites at least.\nFiring nuke? not necessary..the nukes are carried by vehicle.... totaly undetectable....and so much more cheaper...

There is no difference...some people say nuke because that was the term used in the 1960's...there is a difference between atom bombs and hydrogen bombs...atom bombs use uranium as the "fuel" (catalyst), it being a very "heavy" atom (atomical weight) while the hydrogen bomb as the name implies uses hydrogen as its catalyst which is very light.

There is no right answer. \n\n Many sources offer different answers, and depending on the source, there are 189, 191, 192, 193 or 194 independent countries in the world today. \n\n The United Nations has 191 members (including East Timor, the newest nation) but that number does not include the Vatican, an independent nation. \n\n The US State Department recognizes 192 independent countries around the world. but that list of countries reflects the political agenda of the United States of America. As an example, it does not include Taiwan as China claims that Taiwan (the ROC) is simply a province of China. \n\n Many World Almanacs use 192 countries, which is probably the best answer, but what about East Timor? Palestine? Greenland? Western Sahara? The political world is constantly changing.

First three answers are not correct.  The answer, for normal hydrogen and helium, is four.  Two of the protons will convert to neutrons, with the emission of positrons and neutrinos.  The positrons will annihilate with two of the original hydrogen electrons, each throwing a pair of 511 kev gamma rays.  The remaining two electrons will tie up with the helium.  This is the reaction that powers the sun.

yes there are many start with hydrogen and then move up the periodic table of ELEMENTS\n\nsorry for the pause ( the boss walked by )

193 countries-it depends\n\nIf you said INDEPEDENT countries...

By Most Accounts, 193 is the Correct Answer\n\nA very frequent geographical question is "How many countries are in the world?." Different numbers pop up when one inquires or reads about the number of countries in the world. Each source you use often yields a different answer.\nUnited Nations\n\nThere are 191 members of the United Nations. Unfortunately, the number 191 is too often used to represent the number of countries in the world. Although this number represents almost all of the countries in the world, there is still one country (the Vatican City) that is independent and has chosen not to become a member of the U.N.\n\nU.S. Department of State\n\nThe United States' State Department recognizes 192 independent countries around the world. \n\nTheir list of 192 countries reflects the political agenda of the United States of America and its allies. Missing from the State Department's list is one entity that may or may not be considered a country, depending on who you talk to.\nThe One Outsider\n\nTaiwan meets most of the requirements of independent country or state status. However, due to political reasons, it fails to be recognized by the United States and much of the rest of the world.\n\nTaiwan was actually a member of the United Nations (and even the Security Council) until 1971, when mainland China replaced Taiwan in the organization. Taiwan continues to press for full recognition by other countries, to become "part of the club" and fully recognized worldwide but China claims that Taiwan is simply a province of China.\n\nThus...\n\nYour Guide considers there to be 193 countries, which is probably the best current answer to the question, "How many countries are in the world?" unless Taiwan is officially absorbed into China at some point, in which case the answer would be 192.\n\nHowever...\n\nRecognize that there are dozens of territories and colonies that are sometimes erroneously called "countries" but don't count at all - they're governed by other countries. Places commonly confused as being countries include Puerto Rico, Bermuda, Greenland, Western Sahara, and even the components of the United Kingdom (such as Northern Ireland, Scotland, Wales, and England - sorry folks, they're not countries, states, or nation-states).
