Q.2
The
Pauli Exclusion Principle
states that:
No two electrons can occupy the same quantum state
Two electrons can occupy the same quantum state but no more than two
No two electrons can occupy the ground state, but this is ok for excited states
No two photons can occupy the same quantum state.Slide4

Q.4
Which of the following statement is true?
The Zeeman effect refers to the
splitting of atomic energy levels
in the presence
of
an electric
field.The Zeeman effect refers to the splitting of atomic energy levels in the presence of a magnetic field.The Zeeman effect refers to the splitting of atomic energy levels under applied pressure in one-directionThe Zeeman effect refers to the splitting of atomic energy levels at high temperature.
