When does covalent bonding occur?
Between two non metal atoms
How are atoms covalently bonded?
Electrostatic attraction between nuclei of two atoms and the bonding electrons of their outer shells. Electrons are only shared
What are the types of covalent bond?
Single, double, triple
Why can expansion of the octet not occur in periods 1 and 2?
They do not have a 3D subshell
What is the expanded octet rule?
Elements in period 3 or below can expand their octets by using space in the 3d orbital to accommodate 10 or 12 electrons in their outer shells
What are double covalent bonds?
Four electrons shared in a double bond,
When are coordinate bonds/ dative bonds formed?
One atoms provides both electrons, atoms accepting the pair is electron deficient (no full outer shell of electrons) atom donating has electrons not being used (lone pair)
