The subsequent filling of the 'd' subshells.

Wouldn't that be all you needed to say?

Transition elements have electrons in the d-orbitals. The d subshell contains 5 orbitals. By pauli's exclusion principle, each orbital holds upto 2 electrons. Therefore, 10 altogether. That is, per shell.

a vcaa report said due to the systematic filling of the d subshell, thought it was a bit to simple but would that be it, for a 1 mark q
