Respuesta :

you have the electron configuration [Ar]4s23d104p5

Answer:

2

Explanation:

each orbital has a maximum of 2 electrons, and there are one 4s and five 3d orbitals, both those subshells are doubly-occupied in each orbital, seeing as how there are 2 electrons in the 4s orbital and 10 in the 3d orbitals.
