Explanation:
Vanadium is in Period 4 and in the d-block of elements. The highest energy subshell is 4s. (because as electrons fill the 3d subshell, the subshell becomes of lower energy than 4s)
We have 1s²2s²2p⁶3s²3p⁶3d³4s².
Answer:
Vanadium (V) --- d-block element
Location on the periodic table :
- 4th Period
- 5th Group
Atomic number=23
Atomic mass=51 g/mol
The correct electron configuration for Vanadium is:
V= [Ar]4s²3d³ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³
3. 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³ is the right answer.
