C=

3 × 10^8 m / s

Planck's constant

6.626 x 10^-34

Pauli Exclusion Principle

An atomic orbital may describe at most two electrons, each with opposite spin direction

Aufbau Principle

An electron occupies the lowest-energy orbital that can receive it

Niels Bohr

Danish physicist who studied atomic structure and radiations

D=

Double-dumbell shaped orbitals, contains up to 10

P=

Dumbell-shaped orbitals, contains up to 6

F=

Flower shaped orbitals, contains up to 14

SI unit of cycles

Hertz

How is frequency represented

V (nu) number of wave cycles

electromagnetic radiation

a form of energy that exhibits wavelike behavior as it travels through space

Bohr Theory

an electron is found only in specific circular paths or orbits around the nucleus

Schrödinger equation

an equation that describes how the quantum state of a physical system changes with time

speed of light

c=λv

The product of the frequency and the wavelength of a wave equals the

constant (c)

Hund's Rule

electrons occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible

radiant energy

energy carried by light speed up to 3 x 10^8 per second

E=hv

energy equation

what is wavelength represented by

lambda (λ) distance between crests

Erwin Schrödinger's Model

model determines how likely it is to find an electron in various locations

Bohr Model

model of the atom in which electrons move rapidly around the nucleus in paths called orbits

S=

spherical orbitals, contains up to 2

electron configuration

the arrangement of electrons in an atom

quantum of energy

the minimum quantity of energy that can be lost or gained by an atom

quantum mechanical model

the modern description, primarily mathematical, of the behavior of electrons in atoms
