Chemical queries. Especially for high school teachers

Abstract

My colleague and I disagree on the answer to a quiz question."Identify the following element by its quantum numbers; 3, 2, -2, ->/*•" I say the numbers identify the 3rd energy level, d orbital, 8th element, which is nickel. He says that for nickel, it should be 4, 2, -2, -' A, and so it is in correctly written and can identify no element. Who is correct? Answer
