General Chemistry 1 - Electron configuration of ions - 4

Give the ground state electron configuration for a Pd2+ ion.

What neutral atom is a Pd2+ ion isoelectronic with?

Pd: Z = 46 ⇒ 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d8

Pd2+ ⇒ 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s0 4d8 ⇒ 44 electrons

Ruthenium Ru (Z = 44) is isoelectronic with Pd2+
