Atomic Mass of Vanadium (V)

Quick answer

The relative atomic mass of Vanadium is 50.942 u — the weighted average of its naturally occurring isotopes, on the carbon-12 scale.

Vanadium by the numbers

Z = 23 fixes the protons; the neutron count can vary between isotopes, which is why the atomic mass is an average (50.942 u) rather than a round number.

Atomic mass vs mass number

Mass number (A) counts particles — protons + neutrons in one specific atom, always a whole number. Relative atomic mass is the experimentally measured average over all natural isotopes, so it comes out fractional (50.942). Exams love this one-mark distinction.

Students also ask

Is the atomic mass of Vanadium a whole number?

No. 50.942 u is the average of Vanadium's natural isotopes, which is why it lands between whole numbers. The mass number of a single isotope, though, is always whole.

How many neutrons does Vanadium have?

Neutrons = mass number − atomic number. For Vanadium's commonest isotope that is about 51 − 23 = 28, though the exact count differs between isotopes.
