Chemistry Chapter 5

Question 1

highest/lowest part of a wave

Answer 1

crest/trough

Question 2

wavelength

Answer 2

crest to crest

Question 3

frequency

Answer 3

number of waves that pass a point in 1 sec, shorter wl, higher frequency

Question 4

how fast does electromagnetic radiation travel

Answer 4

speed of light

Question 5

wave equation

Answer 5

c = λ f, speed wl, frequency, m/s

Question 6

photon

Answer 6

energy moving at speed of light, characteristics of both particle and wave, energy proportional to frequency

Question 7

how is energy lost

Answer 7

as a photon

Question 8

energy levels and amount of electrons

Answer 8

s(1-2), p(3-6), d(5-10), f(7-14)

Question 9

orbital

Answer 9

3d space around nucleus where electrons can be found

Question 10

how many sublevels in n=2

Answer 10

2s, 2p

Question 11

how many orbitals in n=4

Answer 11

4s, 4p, 4d, and 4f.

Question 12

each orbital can hold

Answer 12

2 max electrons

Question 13

before you pair off electrons

Answer 13

1 electron in each box

Question 14

electron configuration

Answer 14

different from orbital diagram, has electron above level

Question 15

other things to know

Answer 15

electron chart and configurations on periodic table

Question 16

number of valence electrons

Answer 16

used for dot diagrams, increasing by group

Question 17

atomic radius increases

Answer 17

down and to the left

Question 18

ionization energy

Answer 18

As the distance from the nucleus to the valence electron increases, the ionization energy decreases and less energy is required to remove the valence electron. Ionization increases up and to the right

Question 19

metallic character increases

Answer 19

down and to the left

Question 20

electronegativity

Answer 20

The tendency of an atom in a molecule to attract the shared pair of electrons towards itself, increases up and to the right
