Electronic structure

Question 1

Define: () = importan bits
Electron shell

Sub-shell

Orbital

Answer 1

electron shell = a (group of atomic orbitals) with the same principle (quantum number, n). also known as the main energy level

Sub-shell: a (group of orbitals) of the (same type) within a shell

Orbital: a (region) within an atom that can hold up to (opposite spins) with (opposite spins)

Question 2

what’s the max amount of electrons allowed in each electronic shell

Answer 2

n1 (1st shell): 2 electrons

n2 (2nd shell): 8 electrons

n3 (3rd shell): 18 electrons

Question 3

Describe the SHELL, SUB-SHELL, ELECTRONS, ORBITAL

(in exams orbitals wouldn’t be mentioned just there as reference)

(need to go to notes or one drive -pdf file- to look at -box method/written method)

Answer 3

1 - S - 2 - 1

2 -S P - 2 6 - 1 3

3 - S P D - 2 6 10 - 1 3 5

4 - S P D F - 2 6 10 14 - 1 3 5 7
