You are watching: What happens when an atom loses or gains an electron

logo3. Dividing atomspage 9Atoms shedding bitsThe electrons the whiz about outside the nucleus have actually a negative charge. Lock are held in the atom by the positive charge the the nucleus. This electrostatic attraction is part of one of the an easy forces that nature – electromagnetism.

Interactive atom becoming an ionPicture 3.1 A neutral atom that loses one electron becomes a confident ion.Neutral atomsIn plain matter, the number of electrons in one atom is the exact same as the variety of protons. The optimistic and an unfavorable charges balance every other. Overall, the atom is uncharged (neutral).

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

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

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