Reactions between atoms occur when:
a) an atom seeks to fill its outer shell of electrons
b) an atom seeks to balance its positive and negative charges
c) the reaction will result in paired electrons

select all that apply.

Explanation:

A chemical reaction is a reaction which results in the formation of a new compound. This new compound can be formed by sharing of electrons between the reactants or by donation of electron(s) from one reactant to another.

For example, is a chemical reaction as it leads to formation of new compounds by donation of electrons.

A chemical reaction can also occur when atoms balance their positive or negative charge because during this process there is also exchange of electrons occurring.

Therefore, we can conclude that reactions between atoms occur when:
