AP Chemistry — Sample

An atom of an element has an atomic number of 27. What is the ground-state electron configuration of its most common ion with a +3 charge?

A $1s^2 2s^2 2p^6 3s^2 3p^6 3d^6$

B $1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^4$

C $1s^2 2s^2 2p^6 3s^2 3p^6 3d^7$

D $1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 3d^5$

Explanation. The correct answer is A. To determine the ground-state electron configuration of an ion, you first write the configuration for the neutral atom and then remove electrons. For an atom with atomic number 27 (Cobalt), the neutral electron configuration is $1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^7$. When forming a positive ion, electrons are removed from the orbitals with the highest principal quantum num
