Question

please fill in the missing information with regards to the description of the metal.
your answer
description|noble gas core electron configuration of the neutral atom|chemical symbol of the metal|name of the metal
a metal ion with a net charge of +4 and 1 electron in the 3d shell.

Explanation:

Step1: Determine the electron - configuration of the ion

A metal ion with a + 4 charge and 1 electron in the 3d shell. For a transition - metal ion with a + 4 charge, electrons are removed first from the 4s sub - shell and then from the 3d sub - shell. So the neutral atom must have had 2 electrons in the 4s sub - shell and 5 electrons in the 3d sub - shell. The electron configuration of the neutral atom is [Ar]3d^54s^2.

Step2: Identify the element

The element with the electron configuration [Ar]3d^54s^2 is manganese (Mn).
