what is hydrogen in the periodic table?
532259
Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table. ... Hydrogen gas was first artificially produced in the early 16th century by the reaction of acids on metals.

Lithium is the element that is atomic number 3 on the periodic table. These means each atom contains 3 protons. Lithium is a soft, silvery, light alkali metal denoted with the symbol Li.

Answer and Explanation: Hydrogen is a positive ion. Hydrogen atoms consist of a proton in the nucleus surrounded by one electron.

The hydrogen atom (H) contains only one proton, one electron, and no neutrons. This can be determined using the atomic number and the mass number of the element (see the concept on atomic numbers and mass numbers). Structure of an atom: Elements, such as helium, depicted here, are made up of atoms.

Hydrogen has a proton and an electron. They are not the same as each other but they are the same as the same-named particles found in every other element.

Atomic hydrogen is hydrogen that is stable in the atomic form, that doesn't really form bonds with something else. Nascent hydrogen is a hydrogen atom released during a reaction, and it reacts with something else very, very rapidly.

H contains one proton and three neutrons in its nucleus. It is a highly unstable isotope of hydrogen.
605819
H is another highly unstable heavy isotope of hydrogen. The nucleus consists of a proton and four neutrons. It has been synthesized in a laboratory by bombarding tritium with fast-moving tritium nuclei. One tritium nucleus captures two neutrons from the other, becoming a nucleus with one proton and four neutrons.
671606
H (atomic mass 3.01604928199(23) Da) is known as tritium and contains one proton and two neutrons in its nucleus.

Development of the periodic table. Chemists have always looked for ways of arranging the elements to reflect the similarities between their properties. The modern periodic table lists the elements in order of increasing atomic number (the number of protons in the nucleus of an atom).
1028614
Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1. 00794, hydrogen is the lightest element.
1219617
The periodic table is a system for arranging the chemical elements. ... That number comes from the amount of tiny particles called protons in each atom of the element. The periodic table arranges the elements in rows and columns. In the rows, the elements are placed in order of their atomic number.
1372803
In daily life, when we refer to Hydrogen, we actually refer to H2 or dihydrogen, The molecule made of two atoms of hydrogen (H2) usually in a gaseous form. The Atom of Hydrogen is the first element in the periodic table, with chemical symbol H and the first element created after the Big Bang.

Answer and Explanation: Most elements on the periodic table are metals. Visually inspecting the periodic table shows that most elements are metallic.

Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1. 00794, hydrogen is the lightest element. Besides the common H1 isotope, hydrogen exists as the stable isotope Deuterium and the unstable, radioactive isotope Tritium.
519379
In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).

Hydrogen gas is the most bouyant material on earth. Its molecule H2 has 2 hydrogen atoms with a molecular weight of 2.016 while its nearest competitor, helium is monatomic with a weight of 4.003.
