What is 1s2 2s2 2p6 3s2 3p4 ?

Answer:

1s2 2s2 2p6 3s2 3p4 means that

●s subshell of first orbit or energy level(1s2)has two electrons,

●s subshell of second orbit or energy level(2s2) has two electrons,

●p subshell of second orbit or energy level(2p6) has six electrons,

●s subshell of third orbit or energy level(3s2)has two electrons,

● and p subshell of third orbit or energy(3p4) level has four electrons.





From
1s2 2s2 2p6 3s2 3p4
electron configuration,we get 2+2+6+2 + 4 = 16 electrons.


We know that electron's number is equal to proton number or atomic number for neutral atom.Since here there is no words about charge,we can say that
1s2 2s2 2p6 3s2 3p4

indicates the element whose atomic number is 16.


Now if you look at the periodic table,S has atomic number 16.

So 1s2 2s2 2p6 3s2 3p4 is the electron configuration of Sulphur(S).
