electric charge
Electrons
It becomes negatively charged.
If electrons leave an object it becomes positive. If an object gains electrons it becomes positive. If it has the same types of charges with the same amount it becomes neutral.
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.
It gains electrons!
It gains electrons. So if it gains electrons, then the neutral object becomes negatively charged as well.

It becomes negatively charged.
When it gains or loses electrons, usually by friction with another object.
If electrons leave an object it becomes positive. If an object gains electrons it becomes positive. If it has the same types of charges with the same amount it becomes neutral.
That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
