Expert Solution
Step 1

a)

 

• Calcium is a chemical element whose atomic number is 20 and is placed in group 2 in modern periodic table. 

 

• Calcium is represented by the chemical symbol Ca 

 

• Since, we know that the atomic number of a neutral atom is equal to the number of electrons in the neutral atom. Thus, calcium has 20 electrons in it.

 

• Therefore, the complete electronic configuration of 20Ca is- 

        1s2 2s2 2p6 3s2 3p6 4s2 

 

• This is the required full ground state electronic configuration of calcium.
