electrons can be said to reside in \shells\ which are specified by the principle quantum number. for a given shell, there may exist \subshells\ which are specified with the letters ____________.
o f,g,y,e
o x,y,z
o a,b,c,d
o s,p,d,f

Explanation:

1. The principal quantum number is denoted by the letter 'n' and it determines the energy of atomic orbitals.
2. Sub - shells in an atom are specified by the letters s, p, d, f which correspond to different angular momentum quantum numbers.

Answer:

Question 1: C. n
Question 2: D. s, p, d, f
