It becomes negatively charged.
Electrons have a positive charge and protons have a negative charge. An atom's nucleus is 99.95% of its weight. When an object gains more electrons, it gains a negative charge that over comes the positive charge. This only happens when there are more electrons than protons.
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.

Gains, Positive
Electrons have a positive charge and protons have a negative charge. An atom's nucleus is 99.95% of its weight. When an object gains more electrons, it gains a negative charge that over comes the positive charge. This only happens when there are more electrons than protons.
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
If you mean an atom, if it gains electrons it becomes more negative, so a negative charge. If you really mean an ion, it depends on the charge of the ion.
Its number of Protons is more than Electrons
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
Mass can only be changed if a something loses or gains a bit more stuff, the object has to get bigger or smaller.
