wat is electron affinity in groups  and periods

 

 

wat is ionisation energy in groups  and periods

Divyansh has correctly answered the question. I would like to conclude as:

Ionization enthalpy increases as we go from left to right across the period and it decreases as we go down the group.

Electron gain enthalpy becomes more and more negative as we go from left to right across a period and becomes less negative on going down the group.

@Divyansh,

Good answer keep posting.

in periodic tabe wat is electron affinity in group tat is frm 1-18 and periods tat is frm 1-7

and wat is ionisation in group and period

  • 1

okok i understood

  1. In case of electron affinity increases from left to right in period and decreases down the group.
  2. same with the case of ionisation energy 

 * IMP note: in chemistry there are more exceptions more than examples... :)
