The energy required to remove 1mol of electrons from 1mol of atoms in gaseous state to produce 1mol of ions
1 of 8
First Ionization Energy Trend
ACROSS->INCREASES - increased nuclear charge DOWN-DECREASES - increased electron sheilding
2 of 8
Electronegativity
The ability of the nucleus to attract a bonding pair of electrons
3 of 8
Electronegativity Trend
ACROSS->INCREASE-increase nuclear charge DOWN->DECREASE- increase electron shielding
4 of 8
Atomic Radii
Measured as the half length between two neighboring nuclei
5 of 8
Atomic Radii Trend
ACROSS->DECREASE- increase nuclear charge DOWN->INCREASE-increase electron shielding
6 of 8
Ionic Radii
Can be either bigger or smaller than parent atom Positive ions are smaller as they have lost electrons Negative ions are bigger as they have gained electrons
7 of 8
Amphoteric Oxides
Can display both acidic and basic properties e.g Aluminium Oxide, Silicone Oxide
