Answer 1

1. (a) There are four subshells in the fourth shell, corresponding to the four possible values of l (0, 1, 2, and 3).
(b) These subshells are labeled 4s, 4p, 4d, and 4f.
(c) There is one 4s orbital (when l = 0, there is only one possible value of ml: 0). There are three 4p orbitals (when l = 1, there are three possible values of ml: 1, 0, and -1). There are five 4d orbitals (when l = 2, there are five allowed values of ml: 2, 1, 0, -1, -2). There are seven 4f orbitals (when l = 3, there are seven permitted values of ml: 3, 2, 1, 0, -1, -2, -3).
2. [Ne]3s23p3 is the electron configuration of a(n) Phosphorus (P) atom.
3. All of the alkaline metals have a valence shell electron configuration one.
4. At maximum, an d-subshell can hold ten electrons.
5. The complete electron configuration of sulfur, element 16, is 1s² 2s² 2p⁶ 3s² 3p⁴.
6. The angular momentum quantum number for the outermost electrons in a manganese atom in the ground state is 2.
7. The electron configuration of the valence electrons of an atom in its ground state is ns2np3. This atom is a group 5 element.
