Q.

"An orbital can have 10 electrons”.

1. True

2. False

Q. The ground state electronic configuration of nitrogen atom can be represented by

1. 
2. 
3. 
4. 

Q.

Electronic configuration of $H^{-}$ is

1. 1s¹

2. 1s²

3. 1s¹2s¹

4. 1s⁰

Q.

Any p-orbital can accommodate up to:

1. 2 electrons with parallel spins

2. 2 electrons with opposite spins

3. 4 electrons

4. 6 electrons

Q. An orbital can have 10 electrons

1. True
2. False

Q. The orbital diagram in which both the Pauli’s exclusion principle and Hund’s rule are violated is:

1. 
2. 
3. 
4. 

Q. Any '$p$' orbital can accommodate upto:

1. Four electrons
2. Six electrons
3. Two electrons with parallel spins
4. Two electrons with opposite spins

Q. If Pauli's exclusion principle was not known, the electronic configuration of Lithium atom would be:

1. $1s^{2}2s^1$
2. $1s^{1}2s^2$
3. $1s^3$
4. $1s^{1}2s^{1}2p^1$

Q. If carbon has electronic configuration $1s^6$, it would have lower energy than that of the normal ground state configuration $1s^{2}2s^{2}2p^2$, because the electrons would be closer to the nucleus. Yet $1s^6$ is not observed, since it violates

1. Heisenberg uncertainty principle
2. Pauli's exclusion principle
3. Bohr's postulate of stationary orbits
4. Hund's rule of maximum multiplicity

Q. If the nitrogen atom had an electronic configuration of $1s^7$ it would have lower energy than that of the normal ground state configuration $1s^2,2s^2,2p^3$ because the electrons would be closer to the nucleus. $1s^7$ is not observed because it violates:

1. Heisenberg’s uncertainty principle
2. Pauli's exclusion principle
3. Hund’s rule
4. Aufbau Principle
