Question

The common positive oxidation states for an element with atomic number 24, are ______.

Options

• +2 to +6

• +1 and +3 to +6

• +1 and +3

• +1 to +6

Answer 1

The common positive oxidation states for an element with atomic number 24, are +2 to +6.

Explanation:

The element with atomic number 24 is Chromium (Cr). Chromium shows variable oxidation states because of the availability of multiple unpaired electrons in its 3d and 4s orbitals. The common oxidation states of chromium are +2, +3, +4, +5, and +6. It does not show +1 oxidation state.
