using the aufbau principle, write the electronic configuration for the ground state of the atom having atomic number 1 to 30​

Aufbau principle:

Electrons are added one at a time from the lowest energy orbitals available until all the orbitals are filled.

According to the Aufbau principle, electrons fill lower energy orbitals first.

(i) Boron (Z = 5)

Electronic configuration =  

(ii) Neon (Z = 10)  

Electronic configuration =  

(iii) Aluminium (Z = 13)  

Electronic configuration =  

(iv) Chlorine (Z = 17)

Electronic configuration =  

(v) Calcium (Z = 20)  

Electronic configuration =

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
