Chemistry Chapter 5 And 6

Front 1

Frequency

Back 1

# of waves that pass a given point per second

Front 2

Electromagnetic Radiation

Back 2

form of energy that exhibits wavelike behavior as it stands through space

Front 3

wavelength

Back 3

Shortest distance between equivalent points on a continuous wave

Front 4

electromagnetic spectrum

Back 4

encompasses all forms of electromagnetic radiation

Front 5

Quantum

Back 5

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

Front 6

Planck

Back 6

founded Quantum proposed that emmitted light was quantized.

Front 7

photoelectric Effect

Back 7

electrons, called photoelectrons, arc emitted from a metal's surface when light of a certain frequency shines on the surface

Front 8

Einstein

Back 8

electromagnetic radiation is both wavelike and particle-like

Front 9

Photon

Back 9

particle of electromagnetic radiation with no mass that came a quantum of energy

Front 10

Atoms Emission Spectrum

Back 10

the set of frequencies of the electromagnetic waves emitted by atoms of the element

Front 11

ground state

Back 11

lowest allowable energy state of an atom

Front 12

de Broglie equation

Back 12

predicts that all moving particles have wave characteristics

Front 13

Heisenberg uncertainty principle

Back 13

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

Front 14

atomic orbital

Back 14

3 dimensional region around the nucleus

Front 15

principal quantum numbers

Back 15

indicates the relative sizes and energies of atomic orbitals

Front 16

electron configuration

Back 16

arrangement of electrons in an atom

Front 17

Pauli exclusion priciple

Back 17

the maximum of two electons may occupy a single atomic orbital, but only if the electrons have opposite spins

Front 18

Hund's rule

Back 18

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

Front 19

principle energy levels

Back 19

major energy levels of an atom

Front 20

energy sublevels

Back 20

energy levels contained within a principal energy level

Front 21

aufbau principle

Back 21

each electron occupies the lowest energy orbital available

Front 22

valence electrons

Back 22

electrons in an atom's outermonst orbitals; determine the chemical properties of an element

Front 23

electron-dot structure

Back 23

consists of an element's symbol, representing the atomic nucleus and inner-level electrons, hat is surrounded by dots, representing the atom's valence electrons

Front 24

Balmer series

Back 24

electron morning from higher energy kids to the 2nd orbit = series of visible lines.

Front 25

Lynman Series

Back 25

electron drop into n=1=UV

Front 26

Paschen Series

Back 26

electron drop into n=3=infrared
