Week 12: Quantum Numbers and Electronic Configuratio

Question 1

signified by (n), is the main energy level occupied by the electron. they are described in whole number increments with 1 being the closest to the nucleus.

Answer 1

principal quantum numbers

Question 2

signified as (l), describes the general shape or region an electron occupies–its orbital shape. its value depends on the principal quantum number

Answer 2

angular momentum quantum number

Question 3

signified as (ml), describes the orbital orientation in space

Answer 3

magnetic quantum number

Question 4

describes the spin for a given electron. an electron cannot have zero spin.

Answer 4

spin quantum number

Question 5

an electron occupies orbitals in order from lowest energy to highest

Answer 5

Aufbau Principle

Question 6

eliminates the boxes and arrows of orbital filling diagrams

Answer 6

electron configuration notation

Question 7

states that orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron and that each of the single electrons must have the same spin

Answer 7

Hund’s rule

Question 8

two particles with the spin half of unity can not share the same quantum state at the same time

Answer 8

Pauli exclusion principle
