Electrons and Bonding
Orbital filling order
1s, 2s, 2p, 3s, 3p, 4S, 3D, 4p, etc
- within each shell, the new type of sub shell added has a higher energy.
- the 3d sub shell is at a higher energy level than the 4s sub shell
- therefore 4s sub shell fills before 3 d
-
-
Ionic Bonding
- The electrostatic attraction between
positive and negative ions.
- between metal and non-metal
High boiling point and High melting point because a lot of energy is needed to overcome the strong electrostatic attraction between oppositely charged ions
-
-
Covalent Bonding
- The electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms
- between 2 non-metal
- the overlap of atomic orbital, each containing one electron, to give a shared pair of electrons
- the shared pair of electrons is attracted to the nuclei of both the bonding atoms
- the bonded atoms often have outer shell with the same electron structure as the nearest noble gas
-
Giant Covalent
-
-
Some Covalent lattices can conduct electricity like graphite/graphene but not like diamonds or silicon
-
-
-
Electrons have opposite spins because they are negative therefore they repel each other.
electrons have spin which is either up or down
