Why are atoms electrically neutral?
The neutrons balance out any charge.
There are more neutrons than protons or electrons.
Protons and electrons are equal, thus cancel each other out because they have opposite charges.
Neutrons have no charge which makes the who atom neutral.

protons.
neutrons.
electrons.

gained an electron.
An ion with a negative charge has __________.
the same number of protons and electrons.
lost a proton.
lost an electron.
gained an electron.
