25
how is light produced in an atom
atom is excited, absorbs energy , falls back, photon is released
26
florescence
UV light is converted to visible light, whining and bulbs is converted to UV lights, white clothing is treated, money and driver license has stamps
27
phosphorescence
electrons take several seconds to cascade down,
28
frequency
occurrences of a repeating event per unit timeline
29
c
speed of light m/sec
30
h
wavelength m,nm,angstrom
31
V
frequency 1/sec
32
E
energy cal
33
h- real h
plancks constant cal/sec
34
s
cylinder
35
p
peanut
36
d

37
what is the difference between the 1s and 2s orbital
the 2s is larger
38

2
39
how many enelctons can the s p d f
2,6,10,14
40
anion
when an atom gains electrons
41
cation
when an atom looses electrons
42
will bromine gain or lose electrons
gain 1
43
periods
a row
44
family of elements
column
45
when moving across from left to right what happens to the radius
smaller
46
do you move down the table what happens to the radius
larger
47
most reactive metal
Francium
48
most reaction nonmetal
fluorine
49
why are periods arranged together
same valence electrons
50
reactivity as you go down the left side
more reactive
51
reactivity as you go down the right side
less
52
valence election of an atom says
highest principal level
53
Metal
malleable, conducts electricity, luster, ductile, electron doner, makes up majority
54
nonmetal
brittle, electron acceptor, insulator
55
how are periods arranged
how many electrons are present
56
ionization energy
energy needed to knock a valence electron off
57
solubility
polar desolves polar | no polar desolves nonpllar
58
