Question

Explain the trend in ionisation enthalpy with reference to group 16
​

Answer 1

Answer:

atom and ionic radii:The ionic and atomic radius increases as we move on from oxygen to polonium.

Explanation:

1. ionisation enthalpy decreases with increase in size of the central atom.Therefore it decreases as we move from oxygen to polonium since the size of the atom increases as we move down

Answer 2

Answer:

Ionisation enthalpy

The ionisation enthalpy of group 16 elements has quite high values.

i) Tonisation enthalpy decreases down the groupnfrom oxygen to polonium. This is due to the increase in atomic volume down the group.
