Question

State the electronic configuration of the following elements and state whether they are metals, non-metals, or inert gas.

${}_{18}{}^{}\mathrm{E}$

Answer 1

Electronic configuration — The distribution of an electron in a given shell, orbital, or sub orbitals is known as electronic configuration.

• The arrangement of electrons in energy levels in the shell of the atom.
• The electronic configuration is also known as the electronic structure.
• It also helps to predict whether the element is a metal, non-metal, metalloid, or inert gas.
• If their outermost shell has 8 electrons are considered an inert gas.
• The electronic configuration of the given element E is 2,8,8.

Thus, ${}_{18}{}^{}\mathrm{E}$ — 2,8,8 the element is Argon, is a noble gas.
