Properties of Covalent, Covalent molecular/network, Ionic and Metallic compounds.

Question 1

What are properties of covalent molecular substances?

Answer 1

Non-conductors of electricity, low melting and boiling points, liquids or gases at room temperature, solids are soft and easy to mold, only the polar molecules are soluble in water.

Question 2

What are properties of ionic compounds?

Answer 2

Hard and brittle, high melting and boiling points, solids at room temperature (unless dissolved), can conduct electricity in a solution or as a liquid, soluble in water but not petroleum.

Question 3

What are the properties of metals?

Answer 3

Shiny, hard, sonorous(can make sound), compact/rigid shape, high melting and boiling points, conducts heat and electricity, malleable(can be flattened into sheets without breaking) and ductile(can be stretched into wires).

Question 4

What are the properties of covalent network compounds?

Answer 4

Non-conductors of electricity, very hard, solids at room temperature, high melting and boiling points, insoluble in everything.
