Which is the last element in the series of the actinoids ? Write the electronic configuration of this element comment on the possible oxidation state of this element.

Explanation

`Lr Z= 103` , is the last element of actionoid series its electronic configuration is `[Rn]^(86) 5f^(14) 6d^(1) 7s^(2)`
the possible oxidation state shown by is it + +3
