2
What is the definition of matter?
3
Matter is anything that has MASS and takes up
SPACE.
4
All elements that make up matter are made of
___________.
5
All elements that make up matter are made of
ATOMS!
6
Name the parts of the atom. (4 out of 5 will be
good enough)
7
Parts of the ATOM1. Proton2. Electron3.
Neutron4. Nucleus5. Electron Cloud
8
What is the central part of the atom?
9
Nucleus
  • Extra 100 points
  • Is the nucleus positively charged, negatively
    charged, or have no charge?

10
An atom of an element with the atomic number 6
always has 6 ____________.
11
An atom of an element with the atomic number 6
always has 6 PROTONS.
12
A substance whose smallest unit is made up of
atoms of more than one element bonded together is
called a ____________.
13
A substance whose smallest unit is made up of
atoms of more than one element bonded together is
called a COMPOUND.
14
When two or more substances come together but
dont combine to make a new substance, a
__________ is the result.
15
When two or more substances come together but
dont combine to make a new substance, a MIXTURE
is the result.
16
Name 3 examples of compounds.
17
Examples of Compoundssalt, carbon dioxide,
water, hydrochloric acid, sugar
18
Is a solution an example of a mixture or a
compound?
19
A solution is an example of a mixture.
20
What is the difference between a heterogeneous
and a homogeneous mixture?
21
Homogeneous Mixture the same throughoutHeterog
eneous Mixture parts are different from one
another
22
An element is a pure substance. How many kinds
of atoms make up an element?
23
An element is a pure substance that is made up of
only 1 kind of atom.
24
Name 3 elements and their element symbols that
you have learned.
25
Elements SymbolsSodium NaChlorine ClHydrogen
HOxygen OMagnesium MgSulfur S
26
What are the two major categories for the
elements that make up the periodic table?
27
We can classify the elements of the periodic
table as METALS NONMETALS.
28
What are the columns and rows on the periodic
table called?
29
Columns - Families or GroupsRows - Periods
30
Which of the following is a characteristic that
is typical of a solid, nonmetal element?Shiny,
brittle, good heat conductor, or good electrical
conductor?
31
Nonmetal solids are BRITTLE!
32
___________ change change in which the form or
appearance of matter changes, but not its
composition.
33
Physical change change in which the form or
appearance of matter changes, but not its
composition.
34
Correct this statement to be trueA physical
reaction produces a new substance that has
properties different from those of the original
substance.
35
A CHEMICAL reaction produces a new substance
that has properties different from those of the
original substance.
36
What is an example of a chemical reaction that
has been demonstrated or talked about in class?
37
(No Transcript)
38
What does not affect reaction rate?Surface area,
Balancing it, Temperature
39
Balancing the Equation does not affect the
reaction rate.
40
A beaker water in sunlight becomes warm. Has a
chemical reaction occurred? Explain.
41
No. A chemical reaction did not occur because
there is no change in the identity of the water.
42
What is evidence that a chemical reaction has
occurred?
43
Some evidences of a Chemical ChangeColor
changeCreation of a gasTemperature change
44
Why could being in a closed space with a fire be
hazardous, even if you are in no danger of being
burned?
45
As the fuel burns, it consumes oxygen and
produces smoke. Thus, being confined with a fire
can lead to suffocation, not only from lack of
oxygen, bur also from smoke inhalation.
46
Elements that are shiny, malleable, ductile, good
conductors of heat and electricity, and make up
most of the periodic table are what?
47
Elements that are shiny, malleable, ductile, good
conductors of heat and electricity, and make up
most of the periodic table are METALS.
48
What is the ratio of sulfur atoms to oxygen atoms
in SO2?
49
12 is the ratio of sulfur to oxygen in SO2 .
There is 1 sulfur atom and 2 oxygen atoms.
50
Describe how the mass numbers, or atomic masses,
listed on the periodic table for the elements are
calculated.
51
Each atoms mass number is the number of protons
plus the number of neutrons.
