The energy required to remove one mole of
electrons from each of one mole of gaseous atoms
Ionisation energy
to form one mole of positive gaseous ions
(Endothermic)
Across a period, i.e increases as there is no increase
in shielding but an increase in atomic number
Trends of Ionisation
Decrease down a group due to increased shielding
Energy
reducing the electrostatic force of attraction from
the nucleus
Al - Between groups 2,3... first electron in p orbital
- increase in shielding
Drop at 2,3
- reduce forces of attraction
- less energy required to remove
P - between groups 4-5 there is a drop
- First electron pairing
Drop at 4,5
- increased repulsion
- less energy is required to remove an eleccte
Atoms with the same atomic number but a different
mass number
Isotopes
- do not react differently as same electron
configuration
-Atomic Radius
-Shielding
Factors Affecting I.E
-Effective Nuclear Charge
-Proton Number
Incomplete Reactions
Not 100% yield because... Unwanted side reactions
Products lost as gases
Water - hydrogen bonds continuously broken and
reformed
Ice - hydrogen bonds kept in a fixed position so are
Ice less dense than water
slightly longer
Increased distance causes ice to be less dense and
float
Measure of heat content of a substance under
Enthalpy
constant conditions
