Ion electron configuration | Ionic and Covalent Compounds

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

What neutral atom is a Pd2+ ion isoelectronic with?

Pd: Z = 46 ⇒ 1s22s22p63s23p64s23d104p65s24d8

Pd2+ ⇒ 1s22s22p63s23p64s23d104p65s04d8 ⇒ 44 electrons

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