Say you have a hydrogen atom. If you stripped away its last electron, what will happen to it?

A normal Hydrogen atom has one proton and one electron.  If you strip away the electron, you are left with the Hydrogen +1 ion, which is the same thing as a proton.\n\nThere are two other Hydrogen isotopes (much MUCH less common than Hydrogen-1), there are Hydrogen-2 (1 proton, 1 neutron, 1 electron), and Hydrogen-3 (1 proton, 2 neutron, 1 electron).\nIf you were to strip away their electrons, they would still be the a Hydrogen +1 ion, but would be heavier since they have an extra 1 or two neutrons.

It's definitely a proton.  Consider the configuration of a hydrogen atom:  it consists of one proton in its nucleus and one electron orbiting the nucleus.  If you remove the electron to make a hydrogen ion, what do you have left?

An element will become stable when it's outermost electron (valence) shell is full.  In most cases, the valence shell will contain 8 electrons when stable.  Hydrogen and helium only require 2 electrons.  \n\nIn order to achieve a full set, atoms can gain or lose electrons forming ionic compounds.  This normally happens between metals and nonmetals on the periodic table.  Alternatively, atoms can share electrons forming covalent compounds, which generally occurs between two nonmetals.

The previous answer is for K.  For K+ the 4s electron has been stripped away.

An atom is only considered 'reactive' when it needs to lose it valence electrons (for metals) or gain electrons (for non-metals) so as to achieve stability with a full outermost electron shell.\n\nThe first atom you have, [2,8,8], it has a full outermost shell (last number is 8, meaning it has an octet). Thus it is not likely to react and gain or give away any valence electrons. Similarly for your 2nd atom, [2,8].\nThe 3rd atom has only 2 electrons in its 1 and only shell. It has a full outermost shell too (duplet, since 1st shell can only take in max 2 electrons), hence it is stable.\nThe last atom belongs to Group I, with 1 valence electron. Hence it will be very willing to give away its one valence electron to obtain a stable octet.  Thus the last atom is reactive.\nBy the way, the first 3 atoms belong to the noble gases (Group 0).

Yes, then it is a called a cation.  The element still contains its protons and therefore gives the ion a positive charge.  \n\nHowever, the electron configuration of the element determines what ions you can make as the stability will drastically fall with the more electrons removed

Sorry but to divulge Genters location would be futile.  Attempts made at this, will result in your molecules being vaporized and then transformed into 46c4 carbon based atoms, which will then be erased

100% sure\n1. D\n2. B\n3. D (electrons become part of the WATER molecule which eventually reacts with hydrogen to form water)

a proton has a weight of approximately 1836.15 electrons

No, sadly. When you break down the chemical compund water, you would get Hydrogen in a gaseous state. You would have to compress it or cool it to bring it down to the temperature needed for it to condense into a liquid state.\n\nOh yeah, and I'm not sure, but I think the process is called electrolysis.

Not much of an atom if it can't hold onto its electron!

Some atoms do not loose their electrons easily.  These can either share electrons (like carbon usually does) or snatch electrons from other atoms to become negative ions (like Fluorine does).  Most metallic elements easily loose electrons to become positive ions (like sodium Na - e- = Na+).

Yes.  You just begin to take electrons away from the outermost, least stable orbitals.  In this case the first two electrons will come from the 4s2 shell, and then the one from the 3d.  This will leave you with just [Ar], which is a noble gas, and if you remember back to the beginning of chemistry, elements become ionic (gain or lose electrons) because they all wish to achieve this noble gas configuration.

High low is relative and unimportant, Polarity is what matters. You do not allow for the answer opposite potential energy, which is the correct answer an electron has a negative charge and will move towards a positive potential. if you are referring to an electron in an atom at a particular quantum level it will remain at that level until acted upon by an outside force if this force adds energy it will move to a higher energy level, vise-verse. If you want people to take the time to answer a question take the time to define it well!

Say goodbye to matter, I suppose.\n\nWithout electrons (which are negative), all chemical bonds would collapse - so definitley say goodbye to any and all compounds. There goes most materials.  Ditto for chemistry.

It is harder to remove an electron that has more than 1 electron in the shell because of the combined energy that the shell has. A single electron itself does not require a lot of energy to remove, however, when there is more than one, there is combined energy placed in the shell. It is still possible to do so, but is very hard.\n\nTom Walvin\nChemist

It will always have the same number of protons per atom... it protons are added or taken away, it won't be gold anymore.
