You are watching: An atom that gains or loses electrons is called

logo3. Splitting atomspage 9Atoms losing bitsThe electrons that whiz about outside the nucleus have a negative charge. They are held in the atom by the optimistic charge the the nucleus. This electrostatic attraction is component of among the basic forces that nature – electromagnetism.

Interactive atom ending up being an ionPicture 3.1 A neutral atom the loses one electron i do not care a confident ion.Neutral atomsIn plain matter, the variety of electrons in one atom is the very same as the number of protons. The confident and an adverse charges balance each other. Overall, the atom is uncharged (neutral).

However, if something wake up to make an atom shed or gain an electron climate the atom will no longer be neutral.

Atoms or ionsAn atom that gains or loser an electron i do not care an ion. If the gains a negative electron, it becomes a negative ion. If it loses an electron it i do not care a optimistic ion (see page 10 for much more on ions).

When a entirety group of atoms (usually as part of an insulator) acquire or lose electrons, this will reason static electrical energy (see web page 11 for an ext on electrostatics).
