What causes ionisation?

Answer 1

When the atom loses a balancing electron or gains an unbalancing electron.

For instance, there is one proton in hydrogen. To be electrically neutral (or balanced), there has to be one electron. If you magnetically strip the electron from hydrogen, you get an H+ ion which is electrically positive. If you force an electron into the hydrogen atom through centrifuges, etc, you have an H-. One electron has one - charge, and one proton has one + charge. The +'s must balance the -'s, otherwise you have an ion.

Answer 2

Unless the element is a noble gas, it does not have a full valence shell, and is unstable. In order to fix this, it either loses or gains electrons giving it a charge. For example, Sodium needs to lose 1 electron in order to be stable, so by losing it, it gains a positive charge. Or, compounds can go under ionisation, for example hydrochloric acid. When put in solution, the H and Cl atoms, separate from each other, and become H+ and Cl- ions.

Answer 3

Ions form ionic bonds due to charge attraction.

Answer 4

Charge attraction is what causes ions to form to ionic bonds. This is learnt in science.

Answer 5

Ionization occurs when particles lose or gain electrons.

Answer 6

Charge attraction
