metals have a tendency to lose electrons while nonmetals have a tendency to gain electrons. Metals are located left of the stair-step line and non-metals are located to its right.
The halogens
An element in group 16/VIA, such as oxygen, is most likely to gain two electrons when forming an ionic bond. This is due to the fact that the atoms of the elements in group 16/VIA have six valence electrons and require two more to get a filled valence shell of 8 electrons (octet rule).
Representative elements will gain or loose electrons until the atom has 8 electrons in its outer most shell or ( outer most electron level).
metals
These are covalent compounds formed by sharing electrons.
their gain or loss of electrons

OXYGEN because it has only one oxidation state of -2, all the other elements in the group have multiple oxidation states.
Calcium is most likely to lose two electrons to form its dipositive ion.
Bromine will gain one electron.

there is not a definite chemical but it will most likely be in the carbon family (column) because it is right in between noble gases which is what elements are trying to lose and gain electrons to become I hope that helped :)
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.
That depends on the reaction, and the gain of electrons is refereed to as reduction.

Nonmetals, expecially halogens.
