You are watching: When an atom loses an electron, what happens?

logo3. Splitting atomspage 9Atoms shedding bitsThe electrons that whiz around external the nucleus have a negative charge. They are held in the atom by the positive charge of the nucleus. This electrostatic attractivity is component of one of the fundamental pressures of nature – electromagnetism.

Interenergetic atom becoming an ionPicture 3.1 A neutral atom that loses an electron becomes a positive ion.Neutral atomsIn simple matter, the number of electrons in an atom is the exact same as the variety of proloads. The positive and also negative charges balance each various other. Overall, the atom is uncharged (neutral).

However, if something happens to make an atom shed or gain an electron then the atom will certainly no longer be neutral.

Atoms or ionsAn atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (watch web page 10 for even more on ions).

When a whole team of atoms (usually as part of an insulator) obtain or shed electrons, this will certainly cause static electrical power (watch page 11 for even more on electrostatics).
