Question

Assertion - Reason

A) Number of orbitals in 3rd shell is 9.

R) Number of orbitals for a particular value of n=n^2.​

Answer 1

Answer:

Explanation:

i think assertion is correct and reason is wrong

There are four orbitals in the n = 2 shell. There is only one orbital in the 2s subshell.

Answer 2

total number of orbitals in nth shell =n2

where n=shell/principal quantum number

total number of orbitals in third shell=32=9

so these orbitals are 13 - orbital 33 p - orbitals and 5 third orbitals
