Problem: The orbital diagram that follows shows the valence electrons for a 2+ ion of an element. What is the element?

FREE Expert Solution

We are asked to find the identity of the +2 ion for the given valence electron configuration:

Recall that every single element in the periodic table has a corresponding atomic number.

The atomic number of an element is always equal to the number of protons of that element. And when the element is neutral (charge = 0), the number of protons is equal to the number of electrons.

Neutral element:          Atomic number = # protons = # of electrons

Problem Details

The orbital diagram that follows shows the valence electrons for a 2+ ion of an element. The 4d subshell contains five orbitals.  The first has two arrows, one pointing up and one pointing down.  The remaining orbitals all contain one arrow, each pointing up.

What is the element?
