Question

The quantum number which explains about size and energy of the orbit or shell is: [ ]a) n
b) l
c) ml
d) ms

Answer 1

Answer:

a

Explanation:

principle quantum number gives size of the orbit as r(n)=0.53×n^2÷Z . energy of nth orbit as _13.6×Z^2÷n^2

Answer 2

Dear Student,

◆ Answer -

The quantum number which explains about size and energy of the orbit or shell is n.

● Extra information -

• Quantum numbers describe the unique quantum state of an electron of an atom.

There are 4 quantum numbers -

(1) Principal quantum number (n)

(2) Azimuthal quantum number (l)

(3) Magnetic quantum number (ml)

(4) Spin quantum number (ms)

Thanks dear. Hope this helps you...
