A
Covalent Bonding
2
Q
What is a covalent bond?
A
A covalent bond is a shared pair of electrons between two non-metal atoms. It is the electrostatic force of attraction between the positively charged nuclei of each atom and the negatively charged electrons.

Q
What are diatomic molecules/elements?
A
Pure elements that form molecules consisting of two atoms bonded together
4
Q
Name all 7 of the diatomic elements
A
- Iodine
- Bromine
- Chlorine
- Fluorine
- Oxygen
- Nitrogen
- Hydrogen
5
Q
Explain why covalent molecules have low melting and boiling points
A
The weak intermolecular forces (forces between molecules) only require a small amount of energy to break, which means they’ll break at low temperatures.
