Chemistry C2
- chemical bonding
- Covalent
bonding-When atoms
of non-metallic
elements join
together by sharing
electrons
- When two atoms share a pair of electrons
- When two atoms share a pair of electrons
- Ionic bonding-(metallic
elements) Ionic compounds
are held together by strong
forces between the
oppositely charged ions.
- Giant ionic structures
- High melting points, conduct electricity when dissolved in water.
- High melting points, conduct electricity when dissolved in water.
- Giant covalent strutures
- Covalently bonded
substances with giant
structures have very high
melting points
- Diamond is a form
of carbon, with
atoms that form four
covalent bonds
- Graphite is another
form of carbon where
the carbon atoms form
layers that can slide
over other
- Graphite can conduct
electricity because of
delocalised electrons
- Graphite can conduct
electricity because of
delocalised electrons
- Graphite is another
form of carbon where
the carbon atoms form
layers that can slide
over other
- Diamond is a form
of carbon, with
atoms that form four
covalent bonds
- Covalently bonded
substances with giant
structures have very high
melting points
- Giant ionic structures
- Formulae
- Charges on ions cancel eachother out
- CaCl2 (one Ca2+ ion for every two Cl- ions
- CaCl2 (one Ca2+ ion for every two Cl- ions
- Charges on ions cancel eachother out
- Simple molecules
- low melting points, boiling points
- No overall charge, can't conduct electricity
- Weak intermolecular forces-low m and b points
- Weak intermolecular forces-low m and b points
- No overall charge, can't conduct electricity
- low melting points, boiling points
- Covalent
bonding-When atoms
of non-metallic
