What is the trend in electron configuration across period 2 and 3
Mpt increases from g1-g4... Sharp decrease between g4-g5 due to structures changing from giant to simple.... then mpt are relatively low g5-g8.... t

Definition of first ionisation energy
The energy required to remove one electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ ions
2 of 5
what is the trend in ionisation energies across a period
Number of Protons increses... Increase in NUCLEAR CHARGE. ATOMIC RADIUS decreases. Negligible SHIELDING change. =increase in nuclear attraction leading to a general increase in ionisation energies
3 of 5
what is the trend in ionisation energies down a group
Number of shells increases SHEILDING increases ATOMIC RADIUS increases NUCLEAR CHARGE is outweighed
