Question

An electron in an atom has m=-2 value. Then 
i) Its 'n' value should be greater than 2
ii) its 's' value should be +1/2
iii) its ll value should be 2
iv) its ll value should be greater than 1 ​

Answer 1

Answer:

it can also be option 4 and 2

Answer 2

An electron in an atom has an m=-2 value. Then its ''l" value should be 1 and its n' value should be greater than 2.

• m is called the magnetic quantum number and l is called the azimuthal quantum number. n is called the principal quantum number and "s" is called the spin quantum number.
• The value of m lies from +l to -l.
• Hence for m=-2, the value of l should be greater than 1 as m has the value from +l to -l.
• Again for l>1 the orbital is d and the value of the principal quantum number "n" should be greater than 2 as the d orbital starts from 3d.
• So, the correct option is iv and i.
