What is A Mineral?
Chpt. 3 Section 1 pg. 66-69
Rocks
are Made of
Minerals
Minerals must be :

inorganic (made of nonliving material)

naturally formed (formed in nature)
it
is a solid
it
is a crystal (has a crystalline structure)
Minerals are made of elements
 Elements
are pure substances
that cannot be broken down into
into simpler substances by
chemical means.

All minerals contain one or more of the 92
naturally occurring elements
Each element is made up of
only one kind of atom.
Atoms are the smallest part of
an element that has all the
properties of that element.
Minerals are also made up of atoms
of one or more elements.

Most minerals are made of compounds of
several different elements.
A
compound is a substance made of
two or more elements that have been
chemically joined, or bonded.

Halite, NaCl, - is a compound of
sodium, Na, and chlorine, Cl
Can you tell me ?
How
(S6CS10.d)
does a
compound differ
from an element?
Answer:
 An
element is a pure substance
that cannot be broken down into
simpler substances by ordinary
chemical means. A compound is
a substance made of two or more
elements that have been
chemically bonded.
copper, gold, and silver
A
mineral that is composed of
only one element is called a
native element.
Crystals are solid, geometric
forms of minerals produced by a
repeating pattern of atoms or
molecules.
Minerals are divided into 2 groups
based on chemical composition.
1.
2.
Silicate Minerals- which contain silicon and
oxygen (make up 90% of the earth’s crustthey combine with other elements, such
as,aluminum, iron, magnesium and potassium,
to make up silicate minerals ---quartz, feldspar,
mica,
Non-silicate Minerals- make up the rest of the
earth’s crust (do not contain silicon and
oxygen)-such as carbon, oxygen, fluorine, and
sulfur, and they combine to make up non
silicate minerals such as -----copper, calcite,
gypsum, galena, corundum,
Can you tell me?
How
S6E.b
do silicate minerals
differ from nonsilicate
minerals?
Silicate minerals contain a
combination of
silicon and oxygen;
Nonsilicate
minerals do not
contain a combination of
silicon and oxygen.
