multiple - choice question\nwhat is the electronic configuration of vanadium(v)\n1s²2s²2p⁶3s²3p⁶4s²3d³\n1s²2s…

Explanation:

Step1: Recall atomic number of Vanadium

Vanadium has an atomic number of 23.

Step2: Write electron - filling order

Electrons fill orbitals in the order 1s, 2s, 2p, 3s, 3p, 4s, 3d. The s - subshell can hold 2 electrons, p - subshell can hold 6 electrons and d - subshell can hold 10 electrons.

Step3: Determine electron configuration

1s²2s²2p⁶3s²3p⁶4s²3d³ accounts for 2 + 2+6 + 2+6 + 2+3 = 23 electrons.

Answer:

1s²2s²2p⁶3s²3p⁶4s²3d³ (the first option in the list you provided)
