When a metal reacts with a non-metal few changes takes place with the compound or molecules undergoing in the reaction. Let us see what happens.
Changes that take place during reaction
When metal reacts with non-metal following changes occurs.
Transfer of electrons
When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. The resulting compound is called an ionic compound.
Formation of ions
The metal atoms give electrons to the non-metal atoms. The metal atoms become positive ions and the non-metal atoms become negative ions.
Few examples of the reaction between metals and non-metals
- Sodium + chlorine → sodium chloride
- Magnesium + oxygen → magnesium oxide
- Calcium + chlorine → calcium chloride
