Question

plz say the answers.....who can first send ...that answer i marked as brainlist​

Answer 1

Explanation:

2) u = sin i / sin r

3) Maximum number of electrons in a Shell is given by 2n²

Therefore in L shell = 2 (2)² = 2 × 4 = 8

4) Pauli's Exclusion Principle

Answer 2

Answer:

Explanation:

(2).N=c/v

n is the refractive index

c is the velocity of light in a vacuum ( 3 × 108 m/s)

v is the velocity of light in a substance

(3).C (8 electrons)

(4).This violates the Pauli Exclusion Principle: No two electrons in the same orbital can have the same spin. You have no electrons in the 2s orbital, which is between the 1s and 2p levels. This violates the Aufbau Principle: When adding electrons to an atom, you put them in the lowest-energy orbitals available.
