1.

Which one is the wrong statement

1A
2B
3C
4D

In H-like atom energy of 2s = 2p orbital. Incorrect
statement is (c).

2.

Which of the following statements does not form part of Bohr's
model of the hydrogen atom

1Energy of the electrons in the orbit is quantized
2The electron in the orbit nearest the nucleus has the lowest energy
3Electrons revolve in different orbits around the nucleus
4The position and velocity of the electrons in the orbit cannot be determined simultaneously

It represents Heisenberg’s uncertainty principle.

3.

Electron occupies the available orbital singly before pairing in
any one orbital occurs, it is

1Pauli's exclusion principle
2Hund's Rule
3Heisenberg's principle
4Prout's hypothesis

electron path

1Hund
2Thomson
3Rutherford
4Sommerfield
