3. Atomic size and its trends

Å = 10^-8 cm = 10^-10 m

Atomic radii ∝ 1 / Nuclear charge

4. Ionisation energy and ionisation potential

M(g) + Energy (IE) → M+(g) + e-

13.6 V × 1.602 × 10^-19 C = 13.6 × 1.602 × 10^-19 J

Ionisation energy = (13.6 × 1.602 × 10^-19) / (1.602 × 10^-19) = 13.6 eV

Successive ionisation energy order: IE3 > IE2 > IE1
