Halogen - Chemical Properties

Oixdising & Reducing Agent trend of Halogens

What is the trend of the Oxidising power of halogen ? + what happens to the halogen

Cl 2 > Br 2 > I2

When a halogen acts as an Oxidising agent , it gain electrons. ( Taken from oxidised species. )

Xe + 2e- —→ 2X-

What factors causes the Halogen to Oxidises ? + what is the trend down the group

down the group : it’s harder to gain an electrons cuz atoms are larger and more shielding due to the extra electron shells

What happen when halide ion is used as reducing agent ?

2 X- —→ 2e- + X2

When halide ions reduces another substances , the halide is oxidises to a halogen .

What is the trend of the reducing power of halogen ? + what happens to the halogen

Cl - < Br - , I -

When a halide ions reduces another act as a reducing agent ,it loses electrons ( give to the reduced species )

2X- —→ x2 + 2e-

What factors causes the Halogen to reduces ? + what is the trend down the group

Down the group easier to lose an electrons cuz the ion are larger / more shielding
