The radius of a hydrogen shell is 0.53Å. In its first excited state, radius of the shell will be:
1. 2.12 Å
2. 1.06 Å
3. 8.5 Å
4. 4.24 Å
Ionization energy of second orbit of will be:
1. 122.4 eV
2. 40.8 eV
3. 30.6 eV
4. 13.6 eV
In the Hydrogen atom, the energy of the first excited state is – 3.4 eV. Then find out K.E(kinetic energy) of the same orbit of the Hydrogen atom:
1. + 3.4 eV
2. + 6.8 eV
3. – 13.6 eV
4. + 13.6 eV
If the energy of the second Bohr orbit of the hydrogen atom is –328 kJ mol–1, the energy of the fourth Bohr orbit would be:
1. | –1312 kJ mol–1 | 2. | –82 kJ mol–1 |
3. | –41 kJ mol–1 | 4. | –164 kJ mol–1 |
