Safety and periodic classification
Safety
Safe handling cannot be inferred from Vanadium's position in the periodic table alone. Laboratory, classroom and disposal decisions must follow the documentation for the exact material and its safety data sheet.
Position and comparison
Vanadium is in period 4, group 5 and the D block. Its direct neighbours by atomic number are Titanium and Chromium. The recorded Pauling electronegativity is 1.63. Periodic trends are compared only through the separately sourced neighbouring values.
Sources and scope
PubChem attributes element data to sources including IUPAC, NIST and IAEA. Quanta stores the referenced snapshot locally and leaves unknown values unavailable.
Where Vanadium sits among the 118 elements
The table compares the reported values for Vanadium with every other element that carries the same value in the snapshot. A rank is not a judgement, it is orientation: it says how unusual this value is across the periodic table.
| Value | Vanadium | Position in the data set |
|---|---|---|
| Melting point | 2,183 K | Rank 14 of 103 elements with a reported value. Highest: Carbon. |
| Boiling point | 3,680 K | Rank 22 of 93 elements with a reported value. Highest: Rhenium. |
| Density | 6 g/cm³ | Rank 58 of 96 elements with a reported value. Highest: Osmium. |
| Electronegativity (Pauling) | 1.63 | Rank 47 of 95 elements with a reported value. Highest: Fluorine. |
| Ionisation energy | 6.746 eV | Rank 56 of 102 elements with a reported value. Highest: Helium. |
All values and ranks come from the PubChem Periodic Table snapshot, retrieved on 2026-07-15. Elements without a reported value are excluded, so the population differs per row.
The neighbours of Vanadium in the periodic table
- Place in the table
- Group 5, period 4, D block. Classified as transition metal, solid at standard conditions.
- Direct neighbours
- Atomic number 23. Preceded by Titanium, followed by Chromium.
- Same group
- Same number of outer electrons, and therefore similar reactivity to Niobium, Tantalum, Dubnium.
- Discovery
- Recorded in the snapshot as: 1801. Who, where and under what circumstances is not part of that record, so this page carries the sourced year and no discovery narrative.
- Oxidation states
- +5, +4, +3, +2. They follow from the electron configuration [Ar]4s2 3d3 and indicate which compounds to expect.
