4 Based on the column number of the element in the periodic table
5 Each atom needs to fill their octet the need to
have 8 electrons in order to meaning
be the most stable
6 A pair of electrons shaved between two atoms
7 Find valence electrons then octet electrons then
then number of bonds then add lone

7 The Lewis model demonstrates that certain combinations
of atoms have full octets which demonstrate that they're
stable
Electronegativity describes now strongly an atom attracts é to
itself which demonstrates now shaved electrons will be distributed
between 2 atoms in a bond electronegativity increases as you
from left to right horizontally and from the bottom to
go the
top vertically
