3. Splitting atomspage 9Atoms losing bitsThe electrons the whiz about outside the nucleus have actually a an adverse charge. They are organized in the atom through the positive charge that the nucleus. This electrostatic attraction is component of among the straightforward forces the nature – electromagnetism.

Picture 3.1 A neutral atom that loses one electron becomes a positive ion.Neutral atomsIn ordinary matter, the number of electrons in one atom is the very same as the number of protons. The hopeful and an adverse charges balance every other. Overall, the atom is uncharged (neutral).

However, if something happens to do an atom lose or gain an electron climate the atom will certainly no much longer be neutral.

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

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

Question 8Look at the number of corpuscle in the atom below. In each case, decide whether the atom is neutral or charged.
