Question

An element contains 5 electrons in M shell whichis the outermost shell .Write its electronic configuration.​

Answer 1

Nitrogen, with its 5 outermost electrons, interacts with hydrogen atoms in a ratio of 1:3, forming ammonia (NH3).

hope it helps!

Answer 2

The electronic configuration is

${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{2} {3p}^{3}$

• The K shell can accumulate two electrons in its 1s subshell.
• The L shell can accumulate eight electrons in its s and p subshell.
• The M shell can accumulate 18 electrons in its s, p and d subshell.
• Here given that M has 5 electrons that means the K shell has two electrons and the L shell has 8 electrons.
• So, its electronic configuration is as follows-
• ${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{2} {3p}^{3}$
