Cards (5)

What is a covalent bond?
The electrostatic attraction between 2 nuclei and a shared pair of electrons between them.
When do covalent bonds occur?
Often between 2 non-metals.
What are the properties of covalent molecules?
Poor conductors of electricity
Gases, liquids or solids with low melting temperatures
Why do covalent molecules have low melting temperatures?
Weak intermolecular forces, and the covalent bonds are only BETWEEN the atoms within the molecule.
Why are covalent molecules poor conductors of electricity?
No free electrons and the molecules are neutral overall
