Schematically show the number of electrons in the various subshells of an atom with the electronic shell structure 1s2s?2p6 3s2 (atomic weight of 24) as well as a second atom with 1s22s2p6 3s23p5 (atomic weight 32). How many protons and neutrons are in the nuclei of these atoms? Are these atoms (relatively speaking) chemically reactive or chemically inert, metals or nonmetals? Explain
