Match of the following column:

	Column-I		Column-II
(a)	Noble gas	(p)	Uranium
(b)	Transition element	(q)	Radon
(c)	Lanthanlde	(r)	Cerium
		(s)	Copper

Radon is a noble gas that belongs to the group 18. Because the ${\mathrm{Cu}}^{2+}$ ion has an incomplete d level, copper is known as the transition metal.
Cerium is the most plentiful lanthanide. It is more plentiful than tin or lead and nearly as abundant as zinc.
