Transcript What Is a Mineral Made Of Power Point Students

Day 2:
• What is a mineral made of?
• What do multiple minerals together make?
• 2 types of Minerals
Mineral Structure
• A mineral is a naturally formed, inorganic solid
that has a define crystalline structure.
• Minerals may be either elements or
compounds.
• Elements are pure substances that cannot be
broken down into simpler substances by
ordinary means.
• A compound is a substance made of two or
more different elements that have been joined
together by a chemical bond.
Atom
An atom is the smallest unit of an element that
maintains the properties of that element.

Ie. Ripping Paper: If I tear a sheet of paper into
tiny pieces, those pieces still maintain the
properties of paper. Likewise, an atom is a
smaller piece of an element, but still keeps all
the properties of that element.

Play Doh Demonstration
• Follow directions.
• Do not play with or throw the
play-doh.
Compound
A compound is a substance
that is made of atoms of two
or more different elements
joined by chemical bonds.

Mineral Structure
• A few minerals, such as gold and silver, are
composed of only one element.
• A mineral that is composed of only one
element is called a native element.
• Native elements are used in communications,
and electronics equipment.
Native Elements
Two Groups of Minerals
• Minerals are divided into two groups based on their
chemical composition.
• Silicate minerals are minerals that contain a
combination of the elements silicon and oxygen
(quartz, feldspar, mica).
• Silicate minerals make up over 90% of the Earth’s
crust.
• Nonsilicate minerals are minerals that do not
contain a combination of the elements silicon and
oxygen ( copper, calcite, fluorite, corundum, gypsum,
galena).
Silicate
• Silicate minerals include the elements Silicon
and Oxygen.
• Other metal elements, such as Aluminium and
Iron, also attach to Silicon and Oxygen to
make other silicate minerals.
• Examples of silicate minerals:
• Feldspar, quartz, mica
Common Silicate Minerals
Nonsilicate
• Minerals that do not have both silicon and
oxygen.
• found in only 8% of the Earth's crust.
• Examples of nonsilicates:
– precious metals: gold, silver, and platinum
– useful metals: iron, aluminum and lead
– precious gems diamond and ruby.
