Question

Draw an electron configuration for an element with 79 electrons. How many of thiselements electrons fall into p orbitals?

Answer 1

An atom with 79 electrons is Au (gold)

Its electronic configuration: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 6s1 or [Xe] 4f14 5d10 6s1.

The number of electrons in p orbitals = 24 electrons
