The minimum amount of energy that can be gained or lost by an atom

Quantum

1

When electrons are emitted from a metals surface when light of a certain frequency shines on it

Photoelectric effect

2

A particle of electromagnetic radiation with no mass that carries a quantum of energy

Photon

3

_______of an element is the set of frequencies of the electromagnetic waves emitted by the atoms of the element

Atomic emission spectrum

4

Lowest allowable energy state of an atom

Ground state

5

The number of each of orbit (n=?)

Quantum number

6

Which element did Bohr come up with a model for?

Hydrogen

7

Model that schrodinger created, treated electrons as waves

Quantum mechanical model of the atom

8

The wave function predicts a 3 dimensional region around the nucleus called the_____

Atomic orbital

9

(N=?) indicates the relative size and energy of atomic orbitals

Principle quantum number

10

N specifies the atoms major energy levels, otherwise known as the

The principle energy levels

11

The arrangement of electrons in the atom

Electron configuration

12

Principle that states that each electron occupied the lowest available energy orbital available

Aufbau principle

13

Principle that states that a maximum of two electrons can occupy a single orbital if they have opposite spins

Pauli exclusion principle

14

States the single electrons with the same spin must occupy each equal energy orbital before additional electrons with opposite spins can occupy the same energy level orbitals

Hunds rule

Consists of the elements symbol representing the nucleus surrounded by dots representing the elements valence electrons

Electron dot structure

16

Hypothesized that particles could also have wavelike behaviors

Louis de broglie

17

States that it is fundamentally impossible to know precisely both the velocity and position of a particle at the same time

Heisenberg uncertainty principle

18

Electrons in the _____ orbital have the highest energy

Outermost

19

Importance of d9/d4 exceptions

Minimizes repulsion
