Periodic table trends: atomic radius, ionisation energy, electronegativity, and electron affinity.

by @openstemUpdated Chemistry
Periodic Table TrendsAtomic radius↑ down a group↓ across a periodIonisation energy↓ down a group↑ across a period(dips at B, O)Electronegativity↓ down a group↑ across a periodF = highest (4.0)Electron affinity↑ across a period(Cl highest in group 17)Cause: extra electron shellvs. increasing Z_effCause: higher Z_eff andsmaller radius → harder toremove outer electronCause: Pauling scaleF most electronegativebecause small size + high Z_eff
