What is a periodic property? How do the following properties
Explain a) Atomic Radius b) Electron affinity c) lonisation​

Answer 1

Answer:

I) if n=1,2,3,4 then l=0,1,2,3

Explanation:

" n " is principal quantum number and " l " is momentum quantum number

relation between them is l=(n-1)

if n=1 l= 1-1

l =0

if n=2 l= 2-1

l= 1

2) The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.

3) (1) minimize the total energy of the electrons, (2) obey the Pauli exclusion principle (3) obey Hunds rule of maximum multiplicity

4)
