Question

I need some help please! Compare and contrast covalent bonds and ionic bonds.

Answer 1

Covalent bonds are formed when two atoms are able to share electrons.

Iroinic bonds are form when two atoms are electrons from each other to complete the bond. This results in a pair of ions.

Covalent bonds:

• Have a definite shape.
• Have a low melting point.
• At room temperature they are in a liquid or gas.
• They occur between two non-metals.

Ionic bonds:

• Have no definite shape.
• Have a high melting point.
• At room temperature they are solid.
• They occur between a metal and a nonmetal.
