Problem: Give the chemical symbol for the element with the following ground state electron configuration. [Ar]4s23d2Write the quantum numbers n and l select all possible values for ml for each subshell of the element.

FREE Expert Solution

When finding the identity of the element, you’ll have to identify the atomic number of that element. 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


Given electron configuration: [Ar]4s23d104p2 (in condensed electron configuration)

 [Ar]4s23d2

Argon (Ar) 

atomic number = 18
# of protons = # of electrons = 18
