Types of bonding

Types of bonding. There are three types of bond that can occur between atoms:. an ionic bond occurs between a metal and non-metal atom (e.g. NaCl). a covalent bond occurs between two non-metal atoms (e.g. I 2 , CH 4 ). a metallic bond occurs between atoms in a metal (e.g. Cu).

Lakeland Intermolecular Forces Review

Lakeland Intermolecular Forces Review. Click on a question to begin. Question 1. Try Again. Strong intermolecular forces lead to high boiling points and low freezing points. Try Again. Correct!. H 2 O has the highest boiling point so it must have the highest intermolecular forces.
