Question

Changes that reorder atoms to form new molecules, such as the reaction between sodium and chlorine ions to form sodium chloride, are known as _______

Answer 1

The reaction is ionization.

Step-by-step explanation:

Ionization is a process in which molecules tends to lose or gain electrons thus acquiring positive or negative charge.

In the case of sodium chloride, acid and base reacts chemically to form the that compound. When hydrochloric acid
`(HCl)` reacts with sodium hydroxide
`(NaOH)`, the positive charged hydrogen
`(H^+)` and negatively charged hydroxyl
`(OH^-)` together form water and gets neutralized.

After evaporation of water, the positively charged sodium
`(Na^+)` and negatively charged chlorine
`(Cl^-)` combines to form solid sodium chloride(NaCl).

Answer 2

These reactions are called ionic reactions.

In an ionic reaction there is an exchange of ions between two atoms or molecules.
