In modern periodic table, the element with atomic number `Z = 118` will be:

A

Uuo, Ununoctium, alkaline earth metal

B

Uno, Unniloctium, transition metal

C

Uno, Unniloctium, alkali metal

D

Uuo, Ununoctium, nobles gas

Text Solution

Verified by Experts

The correct Answer is:
D
`Z = 118 [Rn]^(86)5f^(14)6d^(10)7s^(2)7p^(6)`, as last electron enters in `p`-subshelll, it belongs to `p`-block. Thus its group number will be `10 +2 +6 = 18`. Hence the element is a noble gas.
