Gain of one electron
Krypton tends to neither lose nor gain electrons since it has a full outer electron shell, making it stable.
Lose or gain an electron
No. They gain electrons
For example metals loss electrons and nonmetals gain electrons.
When you lose an electron, you become positively charged because you have more protons than electrons. When you gain an electron, you become negatively charged because you have more electrons than protons. This process is known as ionization.
A stable electron configuration.
Neither. It does not form ions.
Generally metals lose electrons and nonmetals gain electrons.
Sodium will lose 1 electron in its compounds.
