Which of these ions have five d electrons in the outermost d subshell?

Which of these ions have ten d electrons in the outermost d subshell?

Expert Solution

Which of the following has 5 d electrons in the outermost d subshells

Zn²⁺: [Ar] 3d¹⁰
Tc²⁺: [Kr] 4d⁵

Ru²⁺: [Kr] 4d⁶

Fe²⁺: [Ar] 3d⁶

Re²⁺ : [Xe]4f¹⁴5d⁵

Mn²⁺: [Ar] 3d⁵

Y²⁺: [Kr] 4d¹

So, the ions that have 5 d electrons in the outermost d subshellls are: Tc²⁺, Re²⁺, Mn²⁺

Ions that have 10 d electrons in the outermost d subshells:

Zn²⁺: [Ar] 3d¹⁰

Lr²⁺: [Rn] 5f¹⁴ 6d¹

Sc²⁺:[Ar] 3d¹

Y²⁺: [Kr] 4d¹

Tc²⁺: [Kr] 4d⁵

Cd²⁺: [Kr] 4¹⁰

Fe²⁺: [Ar] 3d⁶

So, the ions that have 10 d electrons in the outermost d subshells are; Zn²⁺ and Cd²⁺
