Sodium chloride is an ionic compound - it has a melting point of 800oC whereas chlorine is a gas has a melting point of -1200C. Explain the differences in melting points of these 2 in terms of their structure and bonding

Hold on, our servers are swamped. Wait for your answer to fully load.

Our discussion up to now has centered on types of bonds that involve. This kind of bonding is called ionic bonding (as you are almost certainly already aware). NaCl is a solid at room temperature, with a very high melting point (801 °C), similar highly reactive metal – sodium (Na), and a pale green gas – chlorine (Cl2).

Explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
