Answer to Question #168752 in General Chemistry for Sara

Question

How many electrons are there in a ⁴⁷V³⁺ cation?

Answer 1

V3+ cation has 20 electrons.

Why?

A neutral Vanadium atom has 23 electrons with an electronic configuration of [Ar] 3d3, 4S2

Considering the fact that V3+ is a cation, this implies that it has lost 3electrons which are the unpaired 3 electrons in the 3d orbital..

Hence, this means V3+ has 20 electrons
