Use the formula n2 = max. number of electrons in shell. 42 = 16. 16 electrons.
If you are filling in the electrons it will be in the 4d orbital. If you are removing electrons the first to come out is in the 5s electrons since transition metals lose 's' electrons before 'd' electrons
The valence electrons fill in 4d orbital The electron configuration of yttrium is [Kr]4d15s2.
The element is Yttrium, with the symbol Y
Yttrium (Y) has, for the most part, 39 electrons. In its ion (atom with a charge that has lost or gained electrons) form though, it has 36 electrons.

2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
Niobium (Nb) Because three 4d electrons = 3d^3

10 electrons.

I am pretty sure its Pd (Palladium)

there are 16 orbitals in a n=4 shell *since there are 2 electrons in each orbital, that makes 32 electrons total here
4 Ground state configuration is 5s^1 4^4
