Expert Solution

Based on electronic configuration find out the total number of electrons by counting all the electrons from all the orbitals. This will give the atomic number of element. Then find out the common ion by replacing or additng to outer most electron from orbital as:

(a) 1s22s22p5

Total number of electrons = 9 [atom belongs to this atomic number = F]

common ion = F^-

(b) 1s22s22p63s2

Total number of electrons = 12 [atom belongs to this atomic number = Mg]

Common ion = Mg²⁺

Total number of electrons = 30 [atom belongs to this atomic number = Zn]

Common ion = Zn²⁺

(d) 1s22s22p63s23p64s23d104p4

Total number of electrons = 34 [atom belongs to this atomic number = Se]

Common ion = Se^2-

(e) 1s22s22p63s23p64s23d104p1

Total number of electrons = 31 [atom belongs to this atomic number = Ga]

Common ion Ga³⁺

The electron configurations described in this chapter all refer to gaseous atoms in their ground states. An atom may absorb a quantum of energy and promote one of its electrons to a higher-energy orbital. When this happens, we say that the atom is in an excited state. The electron configurations of some excited atoms are given. Identify these atoms and write their ground-state configurations. (c) 1s22s22p64s1 (d) [Ar]4s13d104p4 (e) [Ne]3s23p43d1
