1
0 Assertion: 4p orbital will be occupied by an electron before 5s orbital
Reason: (n+1) value is higher for 4p than 5s
(a) Assertion: 3s orbital can be described by n=3,1 = 0 and m=0
Reason: No two electrons can have same 4 quantum numbers
(ii) Assertion: If 3d has 5 electrons all the 5 will have either + oras s value
Reason: Electrons in singly occupied degenerate orbitals will have minimum repulsion
when they have parallel spins
(iv) Assertion: Electrons will enter 4s subshell after the 3p subshell gets filled with 3
electrons
Reason: Lower energy orbitals are filled first
