Depends on the atom, remember that metals want to loose all valence electrons and non-metals want to gain electrons so that it has 8 valence electrons (similar to noble gases)
For example Al (Aluminum) is in group 3, it's a metal so it will lose 3 valence electrons making it have a charge of +3 or AL3+.
Another example, F (Florine) has 7 valence electrons, it's a non-metal so it will gain 1 to become stable, making it have a charge of -1 or F1-.
Hope this helps Ya! :-P

∙ 13y agoWhen two or more atoms react they "want" full outer shells. Which vertical group the atom is in, tells you how many electrons it has in the outer shell. Let's use potassium and chlorine.
Potassium is in group 1, so it has only 1 electron in the outer shell. Chlorine is in the halogen group, the group 1 line from the right. It has 7 electrons in the outer shell, and that shell has a capacity of 8 electrons. This means that Chlorine needs 1, and Potassium has 1 more than it needs. In a reaction with these, Potassium would give the electron in the outer shell, the valence electron, to the Chlorine atom, and we would end up with Potassium chloride (KCl).
Lets say we had for instance Calcium instead of Potassium. Calcium is in group 2, so it has 2 more valence electrons than it needs. If Calcium reacted with Chlorine we would need 2 Chlorine atoms. Calcium would give 1 electron to each Chlorine, and we would end up with Calcium chloride (CaCl2).
I hope this information could help :) Just post a message on my message board if there's anything else you want to know.

Is it true or false in the formation covalent or ionic bonds is it the protons that are shared gained or lost?
False -it is the electrons not the protons.
What happens to electrons in ionic and covalent bonding?
Essentially, pairs of electrons are shared in a covalent bond. Generally, it is greatest when atoms display comparable electronegativity. 2055FCCE-0BFC-F902-5F3E-8A1C92C17B91 1.03.01
When electrons cannot be gained or lost they are?
Shared
Are valence electrons lost gained or shared during a chemical reaction?
They are lost.
When chemical compounds form valence electrons are those that may be .....?
They may be lost, gained, or shared.

What do atoms gain or lose when they bond?
If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
Atoms that have gained or lost electrons have charges and are attached to one another forming?
An ionic bond.If electrons are transferred between atoms, then it is ionic, but if they are shared, then it is covalent.
When electrons cannot be gained or lost they are?
Shared
Are valence electrons lost gained or shared during a chemical reaction?
They are lost.
What is the type of atomic bond that exists when valence electrons are lost or gained?
covalent bond
What type of compound forms covalent bonds?
ions. (atoms that have lost or gained electrons)
What is an atom that has lost or gained one or more valence electrons called?
covalent bonds
Which of the following choices occurs in a covalent bond A. Electrons are transferred. B. Electrons are shared. C. Protons are lost. D. Ions are formed.?
Only non-metal+non-metal is considered covalent. Plus, protons are NEVER shared; just the electrons.
How many electrons an atom has lost gained or shared to become stable?
the oxidation number
When chemical compounds form valence electrons are those that may be .....?
They may be lost, gained, or shared.
