The 23rd element in the periodic table is vanadium. The element of group-5 is vanadium and its symbol is ‘V’. Vanadium is a transition element. Therefore, the valence electrons of vanadium are determined differently.

You are watching: How many valence electrons in vanadium

The last shell(orbit) of a vanadium element has two electrons but its valence electrons are not two. This article discusses in detail the valence electrons of vanadium. Hopefully, after reading this article you will know in detail about the valence electrons of vanadium(V).


How many electrons and protons does vanadium(V) have?

The nucleus is located in the center of the atom. Protons and neutrons are located in the nucleus. The atomic number of vanadium(V) is 23. The atomic number is the number of protons.

That is, the number of protons in vanadium(V) is twenty-three. Electrons equal to protons are located in a circular shell outside the nucleus. That is, a vanadium atom has a total of twenty-three electrons.

What are the valence electrons of vanadium(V)?

The 1st element in group-5 is vanadium and this is the d-block element. The elements in groups 3-12 are called transition elements. The valence electron is the total number of electrons in the last orbit.

Valency and valence electrons of vanadium(V)

Also, valency is determined from the electron configuration of the element in the excited state. The electron configuration of vanadium excited state is V*(23) = 1s2 2s2 2p6 3s2 3p6 4s1 3d1 4px1 4py1 4pz1.

Here, The electron configuration of vanadium(V) shows that it has five unpaired (4s1 3d1 4px1 4py1 4pz1) electrons. Therefore, the valency of vanadium is 5. In the same way, the valency of vanadium 2, 3, 4 can be determined. The valency depends on the bond formation. Vanadium 4 and 5 valency is used most of the time.

How many valence electrons does vanadium ion(V2+, V3+) have?

The electron configuration of vanadium shows that the last shell of vanadium has two(4s2) electrons and the d-orbital has a total of three electrons. There are two types of vanadium ions. The ionic state of the element changes depending on the bond formation. V2+ and V3+ ions exhibit more than vanadium atoms.

V – 2e– → V2+

Here, The electron configuration of vanadium ion(V2+) is 1s2 2s2 2p6 3s2 3p6 3d3. The electron configuration of vanadium ion(V2+) shows that vanadium ion has three shells and that shell has eleven electrons (3s2 3p6 3d3). For this, the valence electrons of the vanadium ion(V2+) are eleven.

V – 3e– → V2+

On the other hand, The electron configuration of vanadium ions(V3+) is 1s2 2s2 2p6 3s2 3p6 3d2. The electron configuration of vanadium ion(V3+) shows that vanadium ion has three shells and that shell has ten electrons (3s2 3p6 3d2). For this, the valence electrons of the vanadium ion(V3+) are ten.

Compound formation of vanadium(V)

Vanadium participates in the formation of bonds through its valence electrons. We know that the valence electrons in vanadium are five. This valence electron participates in the formation of bonds with atoms of other elements.

The electron configuration of oxygen shows that the valence electrons of oxygen are six. The vanadium atom donates its valence electrons to the oxygen atom and the oxygen atom receives those electrons.

As a result, oxygen acquires the electron configuration of neon, and vanadium atoms acquire the electron configuration of argon. Vanadium(V) oxide(V2O5) is formed by the exchange of electrons between two atoms of vanadium and five atoms of oxygen. Vanadium(V) oxide(V2O5) is ionic bonding.
