Quantum Numbers (B)

Question 1

describes the arrangement of electrons inside an atom

Answer 1

Electron Configuration

Question 2

most stable arrangement of electrons in an orbital

Answer 2

Ground-State Electron Configuration

Question 3

3 Rules/Principles: How Electrons are Arranged Inside an Atom

protons are added one by one to the nucleus to build up elements, electrons
are added to atomic orbitals in a similar manner where each new electron occupies the lowest energy orbital available.

Answer 3

Aufbau Principle

Question 4

3 Rules/Principles: How Electrons are Arranged Inside an Atom

maximum of two electrons with opposite spins may occupy a single atomic orbital

Answer 4

Pauli Exclusion Principle

Question 5

3 Rules/Principles: How Electrons are Arranged Inside an Atom

states that single electrons with parallel spins must occupy each orbital of equal energy before an electron with an opposite spin can occupy the same
orbital

Answer 5

Hund’s Rule

Question 6

this notation specifies the principal energy level and sublevel associated with each orbital of the atom with a superscript representing the number of electrons in the orbital

Answer 6

Question 7

Kinds of notations:

the electron configuration of ground state atoms is written using a representation of the electron configuration of noble gases

Answer 7

Noble Gas Notation

Question 8

unusually stable elements that are found at the last column of a periodic table

Answer 8
