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
74 electrons in W, atomnumber 74
The valence electrons fill in 4d orbital The electron configuration of yttrium is [Kr]4d15s2.
since it is in period 5 it contains 4d and 3d levels which both hold 10 electrons each. so therefore I (53) has 20 d electrons

10 electrons.
Niobium (Nb) Because three 4d electrons = 3d^3
5
4 Ground state configuration is 5s^1 4^4
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10

Tungsten is a metal element. There are 74 electrons in a single atom.

I am pretty sure its Pd (Palladium)
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
zero - after the 4s orbitals are filled at Calcium, the 3d orbitals start to fill - not until Gallium do the 4p orbitals start to fill.
