1

the absolutely small (quantum) world of the electron behaves differently

than the larger (macroscopic) world

2

explains the strange behavior of electrons.

quantum mechanical model of the atom

3

accurate term for what we refer to as light

visible light

4

the full range of light energies

electromagnetic spectrum

5

examples of the electromagnetic spectrum

gamma rays, x- rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radiowaves

6

two components of light

electric field
magnetic field

7

distance between corresponding points on adjacent waves

wavelength

8

size or height of a wave

amplitiude

9

the number of complete cycles of the wave passing a given point per second

frequency

10

waves interact with each other in 2 ways:

constructively
destructively

11

what is it called when waves pass through a slit comparable to their size, they bend around it

diffract

12

contrsuctive intereference happens when

equal path lengths

13

destructive interference happens when

path lengths differ by lambda/ 2

14

phenomenon in which light striking the surface of metal causes electrons to be ejected

photoelectric effect

15

light is described as a wave whereas in other cases a particle description works better

wave-particle duality

16

light could be described as a collection of packets of energy

photons

17

the particular pattern of wavelengths absorbed and emitted by any element

atomic spectrum

18

atoms can only exist in a few states with very specific energies because

it can only emit certain wavelengths of light as opposed to a continuous spectra

19

while the wavelength increases, the change in energy between levels gets

smaller

20

electrons exhibit what type of behavior

wave length

21

de Broglie's relation allows us to calculate what

wavelengths

22

which model depicts electrons as waves spread through a region of space called an _____

quantum mechanical model
orbital

23

max number of electrons in any orbital

2

24

a function that describes the periodic behavior of a wave

wave function

25

principle quantum numbers

n

26

secondary quantum number (angular momentum quantum number)

l

27

magnetic quantum number

ml

28

describes the main energy level(shell) that the electron occupies

n= principle quantum number

29

larger values of n are orbitals that are ______ away from the nucleus

farther

30

designates the sub level (sub shell) that the electron occupies

l - angular momentum quantum number
