COMPOUNDS, Between positive and negative IONS - Coggle Diagram
COMPOUNDS
IONIC
Metal
Nonmetal
ionic bonding
Transfer
electrons gives or lose electrons, and they become an
ion
valence electrons
Are held together by a
strong attraction
Those forces (in ions) are more
stronguer
than in the molecules
Usually
hard
Higher melting and boiling points
Solids
do
not
conduct electricity
Conduct electricity when the are
dissolved in water
In a
liquid state
COVALENT
Nonmetal
Nonmetal
covalent bonding
When
atoms
(nonmetals)
Share
a pair of electrons to become a
molecule
valence electrons
STATES - MOLECULE
molecular weight
Is the size and
number of atoms
in each molecule
cohesive forces
More weight
Stronger forces
Higher melting
Higher boiling
Usually
soft
Poor conductors
of heat and electricity
Do
NOT
conduct electricity in
water
Lower melting and boiling points

positive
and
negative
