Vanadium Valence Electrons
Why vanadium has 5
Vanadium has 23 electrons, arranged as 1s2 2s2 2p6 3s2 3p6 3d3 4s2. Counting the 4s electrons plus the 3d electrons gives 5, the usual textbook convention for transition metals. Some courses count only the electrons in the outermost shell, which gives 2 for vanadium; check which convention your class uses.
Vanadium is a transition metal in group 5. Counting its outer s electrons plus the d electrons beneath them gives 5, the same as the group number.
What that means for bonding
Transition metals can lose different numbers of these electrons, which is why vanadium shows several oxidation states (+2, +3, +4). When it forms a cation it loses the 4s electrons first.
Electrons per shell: 2, 8, 11, 2. See the vanadium electron configuration and orbital diagram or the full vanadium data sheet.

Vanadium valence electrons FAQ
How many valence electrons does vanadium have?
Vanadium has 5 valence electrons. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d³ 4s²; the count is 2 outer s + 3 d electrons; 2 in the outermost shell. If your course counts only outermost-shell electrons, the answer is 2.
How do you find the valence electrons of vanadium?
Vanadium is a transition metal in group 5. Counting its outer s electrons plus the d electrons beneath them gives 5, the same as the group number.
How many bonds does vanadium form?
Transition metals can lose different numbers of these electrons, which is why vanadium shows several oxidation states (+2, +3, +4). When it forms a cation it loses the 4s electrons first.
