A) [Ne] 3s23p5.
B) [Ar] 4s23d7.
C) [Xe] 6s1.

Answer 1

Answer:

A) Chlorine (Cl)

B) Cobalt (Co)

C) Caesium (Cs)

Hope this helps.

Answer 2

The abbreviated electron configurations that was given in the question belongs to

Chlorine (Cl)

Cobalt (Co)

Caesium (Cs) respectively.

• Electronic configurations can be regarded as the  electronic structure, which is the way an electrons is arranged in energy levels towards an atomic nucleus.

• The electron configurations is very useful when  describing  the orbitals of an atom in its ground state.

• To calculate an electron configuration, we can put the periodic table into sections, and this section will represent the atomic orbitals which is the  regions that house the electrons.

• Groups one of the period table and two belongs to s-block, group  3 through 12 belongs to the d-block, while  13 to 18 can be attributed to p-block ,The  rows that is found at bottom are the f-block

Therefore, electron configurations  explain orbitals of an atom when it is in it's ground state.
