Question

I can't get venedium electronic confrigation,​

Answer 1

Answer:

Electron configurations are the patterns of arrangement of electrons that are associated with a certain molecule or atom. In order to figure the electron configuration of an element, you've got to know the atomic number.

Vanadium's atomic number is 23 which means answer 4 is correct: 1s2 2s2 2p6 3s2 3p6 4s2 3d3. Each of these is based on the letter associated with it, s can hold 2, p can hold 6, d can hold 10 and f can hold 14. However, you need to stop at 23 which is why things stop at 3d3.
