2What is the definition of matter?
3Matter is anything that has MASS and takes up
SPACE.
4All elements that make up matter are made of
___________.
5All elements that make up matter are made of
ATOMS!
6Name the parts of the atom. (4 out of 5 will be
good enough)
7Parts of the ATOM1. Proton2. Electron3.
Neutron4. Nucleus5. Electron Cloud
8What is the central part of the atom?
9Nucleus
- Extra 100 points
- Is the nucleus positively charged, negatively
charged, or have no charge?
10An atom of an element with the atomic number 6
always has 6 ____________.
11An atom of an element with the atomic number 6
always has 6 PROTONS.
12A substance whose smallest unit is made up of
atoms of more than one element bonded together is
called a ____________.
13A substance whose smallest unit is made up of
atoms of more than one element bonded together is
called a COMPOUND.
14When two or more substances come together but
dont combine to make a new substance, a
__________ is the result.
15When two or more substances come together but
dont combine to make a new substance, a MIXTURE
is the result.
16Name 3 examples of compounds.
17Examples of Compoundssalt, carbon dioxide,
water, hydrochloric acid, sugar
18Is a solution an example of a mixture or a
compound?
19A solution is an example of a mixture.
20What is the difference between a heterogeneous
and a homogeneous mixture?
21Homogeneous Mixture the same throughoutHeterog
eneous Mixture parts are different from one
another
22An element is a pure substance. How many kinds
of atoms make up an element?
23An element is a pure substance that is made up of
only 1 kind of atom.
24Name 3 elements and their element symbols that
you have learned.
25Elements SymbolsSodium NaChlorine ClHydrogen
HOxygen OMagnesium MgSulfur S
26What are the two major categories for the
elements that make up the periodic table?
27We can classify the elements of the periodic
table as METALS NONMETALS.
28What are the columns and rows on the periodic
table called?
29Columns - Families or GroupsRows - Periods
30Which of the following is a characteristic that
is typical of a solid, nonmetal element?Shiny,
brittle, good heat conductor, or good electrical
conductor?
31Nonmetal solids are BRITTLE!
32___________ change change in which the form or
appearance of matter changes, but not its
composition.
33Physical change change in which the form or
appearance of matter changes, but not its
composition.
34Correct this statement to be trueA physical
reaction produces a new substance that has
properties different from those of the original
substance.
35A CHEMICAL reaction produces a new substance
that has properties different from those of the
original substance.
36What is an example of a chemical reaction that
has been demonstrated or talked about in class?
37(No Transcript)
38What does not affect reaction rate?Surface area,
Balancing it, Temperature
39Balancing the Equation does not affect the
reaction rate.
40A beaker water in sunlight becomes warm. Has a
chemical reaction occurred? Explain.
41No. A chemical reaction did not occur because
there is no change in the identity of the water.
42What is evidence that a chemical reaction has
occurred?
43Some evidences of a Chemical ChangeColor
changeCreation of a gasTemperature change
44Why could being in a closed space with a fire be
hazardous, even if you are in no danger of being
burned?
45As 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.
46Elements that are shiny, malleable, ductile, good
conductors of heat and electricity, and make up
most of the periodic table are what?
47Elements that are shiny, malleable, ductile, good
conductors of heat and electricity, and make up
most of the periodic table are METALS.
48What is the ratio of sulfur atoms to oxygen atoms
in SO2?
4912 is the ratio of sulfur to oxygen in SO2 .
There is 1 sulfur atom and 2 oxygen atoms.
50Describe how the mass numbers, or atomic masses,
listed on the periodic table for the elements are
calculated.
51Each atoms mass number is the number of protons
plus the number of neutrons.
