24
Q

Suspension + Ex

A

25
Colloid + Ex
A cloudy mixture with particles so small that they can't be easily separated Milk
26
Aqueous Solution
One dissolved in water
27
Chemical v Property Change
Property can usually be undone and chemical you cant
28
Evidence of chemical change
Change in color or odor Bubbles (precipitate) Release of energy (exothermic) Absorption of energy (endothermic) Solid is formed
29
What must we look for in a chemical change
A NEW SUBSTANCE BEING FORMED
30
Aristotle
Believed everything was made of fire, earth, water or air
31
Dmitri Mendeleev
collected 63 elements in his time Ordered them by mass and chemical reactivity
32
Staircase Line
Division between metals and non-metals
33
Metals
Left of Staircase Line - shiny, malleable, ductile
34
Non-metals
Right of Staircase can be solid liquid or gas
35
Metalloids
Elements on staircase line both metal and non-metal
36
Groups/Families Definitions
groupings going down the periodic table similar reactivity
37
Rows/Periods Definition
groups going across periodic table similar mass
38
Names of groups/families
Family 1 - Alkali Metals Family 2 - Alkaline Earth Metals Family 17 - Halogens Family 18 - Noble gas Family 3 to 12 - Transition metals
39
Alkali Metals
very reactive solid 1+ charge
40
Alkaline Earth Metals
reactive solid 2+ charge
41
Halogens
reactive non-metals most are gases 1- charge
42
Noble Gas
Non-reactive gas no charge
43
Transition Metals
numerous different properties numerous amounts of charges
44
Names of rows/periods
6 - lanthanide series 7 - actinide series
45
Lanthanide Series
starts at element 57 3+ charge
46
Actinide Series
starts at element 90
47
Non metal reactivity + most reactive
More reactive the more right (Excludes Noble gases) Fluorine
48
Metal reactivity + most reactive
more reactive when lower and more left francium
49
Atomic Number
-How periodic table is numbered -same amount of protons and electrons in element
50
Atomic Mass
Protons and Neutrons together
51
What does Carbon-14 mean?
It is the element carbon but the mass is 14 instead of 12 like the periodical table says. The protons and neutrons stay the same.
52
Isotopes
Different types of elements Different mass not atomic number. Carbon-14
53
Ions
Atoms with a charge - or +
54
What does it mean if an Ion has a negative charge
Gained Electrons
55
What does it mean if an Ion has a positive charge
Lost electrons
56
What are the subatomic particles
Protons Electrons neutrons
57
What are the subatomic particles
Protons Electrons neutrons
