Expert Answer:

Yes, Ionisation energy decreases down the group beacuse size increases down the group and force of attraction betweeen nucleus and valence electron decreases.
In some cases, it may show different behaviour where the  nuclear charge increases and due to the increase in nuclear charge, the I.E incraeses.
