14) The answer is option(c) -2,-1,0,+1,+2.
The value of ml depends on 'l' value and 'l' value depends on 'n' value. The range of 'l' value is 0 to n-1, range of 'ml' value is -l to l.
When n=3, the 'l' values are 0 to 2 and 'mi' values are -2 to +2. That is -2,-1,0,+1,+2.
15) The answer is option(d) 5
The subshell designated by n=3, l=2 is 3d subshell. The orbitals in 3d subshell are 5. With regardless of the energy level on which the d-subshell is located has 5 orbitals as long as n>=3.
16) The answer is option(c) 3
The number of subshells in the shell designated by n=3 is 3 subshells. Those subshells are s,p,d.
17) The answer is option (d) 16
Because the formula for total number of orbitals in a shell is n2 here n is principal quantum number. And n value in the question is 4, So the answer is 42 =16
18) The answer is option(c) 3.
The value of ml depends on 'l' value and 'l' value depends on 'n' value. The range of 'l' value is 0 to n-1, range of 'ml' value is -l to l. Depending on these ranging values, the minimum value for principal quantum number(n) is 3.
When n=3, the 'l' values are 0 to 2 and 'mi' values are -2 to +2.
19) The answer is option(e) 7
In 5f subshell there are 1 s orbital,3 p orbitals, 5 d orbitals and 7 f orbitals. So there are 7 orbitals in 5f subshell.
20) The energy of an orbital in the hydrogen atom depends on the Principal quantum number (n).
21) The electronic configuration for Calcium is option (b) 1s22s22p63s23p64s2. The atomic number of calcium is 20. In short its configuration is [Ar]4s2
22) The element represented by the given configuration is option(e) Ge (Germanium).
