Transcript
•The following physical properties of the halogens:
appearance and state at room temperature, volatility, and
solubility in water and organic solvents
•The classification of elements into s, p and d blocks
•The electronic configuration of atoms from hydrogen to
krypton in terms of main energy levels and s, p and d atomic
orbitals
Chlorine is everywhere. If you drink a glass of
water, take medicine, clean your teeth or drive to
work… you are unknowingly - perhaps - benefiting
from chlorine compounds.Even your body’s own
digestive system depends upon a chlorine
compound to break down foodstuffs
Bromine is brown
comes from sea (brine)
The halogen salt formers Group 7
iodine
chlorine
Bromine
There is an increase in the strength of the
intermolecular forces
A measure of the ability of an atom to attract bonding
electrons to itself
