Covalent bonds
A A covalent bond is formed by a shared pair of electrons. is formed when two atoms share electrons to obtain a noble gas configuration. Covalent bonding occurs between non-metal atoms.
Covalent bonds are strong and require substantial amounts of energy to break.
Covalent bond: a shared pair of electrons.
Molecule: two or more atoms covalently bonded together.
Two atoms covalently bonded in a molecule.: two atoms covalently bonded together in a molecule. O2, N2 and Cl2 are examples of diatomic molecules.
A covalent bond can be represented as a single line.
These diagrams show a molecule of methane and water both of which share electrons forming single covalent bonds when a molecule is formed.
Some molecules like oxygen share two pairs of electrons to make a double covalent bond.
