It is the valence shell that chemically reacts. This is the farthest out layer. Atoms try to fill it, no matter what charge it will give them. For hydrogen and helium only this shell holds two electrons, the rest eight. For an example take sodium(1 electron in valence) and chlorine(7 electrons in valence) and the chlorine will take the electron in sodium's shell so showing the filled layer of eight below and giving the chlorine eight. This creats a bond between the two as sodium is now negative and chlorine positive they are very attracted to each other and form table salt.

No. Ions of opposite charges come together to form electrically neutral compounds. A compound cannot carry an electric charge.

Do the atoms in a mixture have a set ratio?

Atoms can interact in different manners. Compounds can have the same ratios of atoms combined in different ways producing different properties (cis and trans forms of compounds come to mind). Additionally, many compounds consist of the same elements but in different ratios. Compare Carbon dioxide, a inert waste product of respiration, to carbon monoxide, a gas deadly to humans. Both use carbon and oxygen, but CO2 has an extra oxygen molecule, greatly changing its properties. So in short, no. Atoms can combine in multiple ratios, and even compounds of equal ratios can come together in different manners to produce different compounds.


Is a molecule a compound?

A molecule is an electrical neutral group made of two or more atoms. Also, a compound is a substance made of two or more elements. Thus a molecule can be a compound as long as it is not made of the same element.
