Question

Quantum numbers of an electron in outer most orbit of an atom are given below.

N l ml ms
3 2 0 +1/2
i. Which is the outer most shell of the element?
ii. Write the electronic configuration of the element?
iii. What is the atomic number of the element?
iv. Write the valency of the element?

Answer 1

Answer

option. iv............ . ...

Answer 2

mark me as brainliest answer

The angular quantum number (l) describes the shape of the orbital. ... The allowed values of n are therefore 1, 2, 3, 4, and so on. ... If n = 3, for example, l can be either 0, 1, or 2.
