Réponse

Atoms bond to achieve stable electron configurations.

3Question

Types of Bonds — examples?

Réponse

Ionic, covalent, metallic, hydrogen bonds.

4Question

Ionic Bond — formation?

Réponse

Transfer of electrons between metal and non-metal.

5Question

Covalent Bond — sharing?

Réponse

Atoms share electron pairs to stabilize.
