Title: Everything that has mass and volume is called matter.
1Everything that has mass and volume is called
matter.
What is matter?
_______ Amount of material in an
object Volume __________________________________
_
2Atoms with certain consistent characteristics are
called.
Elements
3Elements Substances that can NOT be broken into
simpler substances
- Symbols Latin and Greek in Origin
- Usually given the 1st letter of the name or the
1st two letters in the elements name as the
symbol - Periodic Table
- Organizes the elements horizontally by atomic
number - Vertically by similar element properties
4Atoms
- Smallest part of an element that has all the
properties of that element - Model
- ___________ moving charged particles with a
negative charge - Protons _________________________
- ___________ in nucleus with no charge
5How are Protons, Neutrons, electrons related?
- ___________ atomic number
- electrons ______________________
- protons neutrons ______________
6Ions Bonding
- ______ An atom with a positive or negative
charge due to loss or gain of an electron - Gain ________________________________
- Loss ________________________________
- Opposites charges attract holding the atoms
together called ____________________ - _______________ electrons are shared by atoms
instead of given up
7But!!!
Not all atoms of the same element are the same,
either.
8Isotopes
9Certain isotopes of elements are ___________, or
__________. (example Carbon-14 and Uranium-238)
These radioactive isotopes of elements allow us
to do absolute-age dating!
10Most substances on Earth are not pure elements
but rather.
???
Compounds
11A Compound is..
A substance ______________________________________
______________________________.
12A Mixture, on the other hand, is
A substance ______________________________________
__________________________________________________
______________________
13Elements by themselves are much less common than
__________, because they tend to combine with
each other to form Compounds.

15Elements and Compounds in their solid form make
up
Minerals
16A _________ is a naturally occurring _________
with a definite chemical composition and a
___________ structure.
17That means that
- It cant be organic in origin
- It cant be a liquid
- and..
- It has to have a crystal structure
18Lets put that in a list format.
1. Minerals are a __________ occurring substance.
2. Minerals are ________.
3. Minerals have ________ ________________________
__________________________.
194. The atoms that make up minerals are arranged
in an orderly ____________________________________

20How many different minerals are there on Earth???
Answer
21Most Minerals are Compounds
___________________________________ Ex Quartz
Silicon and Oxygen Ex Halite Sodium and
Chlorine Ex Galena Lead and Sulfur
Minerals can have only 1 element
- ___________( native element)
- Ex Gold, Silver, Copper, Sulfur, Diamond
22More than ___ of all of the minerals in the
Earths Crust, however, are made up of compounds
containing Silicon and Oxygen, the two most
abundant elements on Earth.
23High Silica content forms light-colored rocks.
While _______ (but only by about 25) Silica
content forms darker-colored rocks.
24How do Minerals Form???
1. Minerals form in cooling ______ chambers
25Different types of minerals crystallize at
different temperatures
Decreasing temperature
___________ Reaction Series
Mineral formation in a Magma Chamber
26(No Transcript)
272. Metamorphic MineralsSome minerals occur as
the result of Recrystallisation and Reaction
within existing rocks which produces new minerals
in response to changes in_____________
__________
283. Some types of minerals form as water
containing dissolved ______ slowly evaporates.
Salt deposits
29How long does it take for minerals to form??
- Minerals in solution in water can form relatively
________ when the water evaporates. - Minerals in magma can form as _______ as the
magma/lava can crystallize (lava can cool in
minutes, while magma can take thousands of years).
30Although there are thousands of different types
of minerals, their crystals come in six basic
types of shapes
- A Crystal is A regular geometric solid with
smooth surfaces called _________________
- The orderly arrangement of ______, _________, or
______, in any mineral determines the shape of
its crystals.
31Cubic
32Orthorhombic
33Tetragonal
34Triclinic
35Hexagonal
36Monoclinic
37Only 30 of the 4,000 known minerals are common.
These 30 minerals are known as the
______________________rock-forming minerals
38Most rock-forming minerals are
\
The percent composition of Silicate minerals in a
rock determines the type of rock it is.
39Rocks that have a low percentage of Silicates are
dark in color, and are called ______ rocks.
- Rocks that have a high percentage of Silicates
are light in color, and are called ______ rocks.
- Rocks are often made of several different _______
40How are minerals most often identified?
- Minerals are most often
- identified by inspecting their
- ___________ and ____________
