CHXI02:STRUCTURE OF ATOM
307452
The shape of the orbital with the value of \(1=2\) and m = 0 is
1 spherical
2 double dumbbell
3 trigonal planar
4 square planar
Explanation:
For \(\mathrm{s}, \mathrm{p}, \mathrm{d}\) and \(\mathrm{f}\)-orbitals, the values of \(l\) are respectively, \(0,1,2\) and 3 . Thus, if \(l\)=2, then the orbital is \(\mathrm{d}\), which is double dumb-bell shaped.

Which electronic level would allow the hydrogen atom to absorb a photon but not to emit a photon?
1 \({\rm{3s}}\)
2 \({\rm{2p}}\)
3 \({\rm{2s}}\)
4 \({\rm{1s}}\)
Explanation:
Because 1s is the lowest possible energy level in hydrogen atom.
CHXI02:STRUCTURE OF ATOM

Which of the following statements concerning the four quantum numbers is false?
1 ‘n’ gives idea of the size of an orbital.
2 “l” gives the shape of an orbital.
3 ‘m’ gives the energy of the electron in the orbital.
4 ‘s’ gives the direction of spin of the electron in an orbital.
Explanation:
m' gives information about orientation of the electron.

Consider the following sets of quantum numbers: Which of the below setting is not permissible arrangement of electrons in an atom?
For a given value of ‘l’ the permissible values of ‘m’ are \({\rm{ - l, - }}\left( {{\rm{l - 1}}} \right)....{\rm{0}}....\left( {{\rm{l - 1}}} \right){\rm{,l}}\) Thus, for \({\rm{l = 2}}\), m cannot have a value of \({\rm{ - 3}}\).
