Question

The highest oxidation state in plutonium (At. no. = 94) is ______.

Options

• + 6

• + 4

• + 5

• + 7

Answer 1

The highest oxidation state in plutonium (At. no. = 94) is + 7.

Explanation:

In plutonium (atomic number = 94), the maximum oxidation state is + 7. It has a wider variety of oxidation states, which is due in part to the fact that the 5f, 6d, and 7s levels have similar energies. In its compound, Plutonium (Pu) can have oxidation states of + 3, + 4, + 5, + 6, and + 7.
