Question

An element X has eight electrons in the outermost shell. The element X behaves as

a) metal b) non-metal

c) inert gas d) metalloid​

Answer 1

Answer:

b) non metal

Explanation:

Electronic configuration of noble gas is (2,8). It has 8 electron in its outermost orbitals.

Element X has 6 electrons in its outermost shell. So, it requires 2 more electrons to attain the noble gas configuration.

Hence, option B is the correct answer.

Answer 2

Answer:

c) Inert gas

Explanation:

inert gases or noble gases have 8 electrons in the outermost shell.
