The Elements of Matter
Matter
Everything on earth is made up of matter.
Matter is anything that has mass and
takes up space.
Dirt is matter. Orange juice is matter.
Even air is matter.
Three Types of Matter
All matter is classified into one of
three groups:
Atoms
All solids, liquids, and gases are made up
of very, very small particles called atoms.
To see an atom,
you would have
to use a VERY
powerful
microscope.
Parts of an Atom
Atoms are made up of even tinier parts
called electrons, protons and neutrons.
How It Moves
The protons and neutrons of an atom
are located in the center of the atom.
Scientists call the center of
the atom the nucleus.
The electrons rotate around the
center in areas called orbitals.
Different Atoms
Atoms have different numbers of
electrons, neutrons and protons
depending on what kind of atom it is.
The different number of neutrons and
protons makes what is called an
element.
Elements
All matter is made up of elements.
Combining two or more elements can make
different types of solids, liquids, and gases.
How many elements are there?
There are 92 elements that occur naturally.
The elements hydrogen, carbon, nitrogen
and oxygen are the elements that make up
most living things.
Some other elements found in living things
are: magnesium, calcium, phosphorus,
sodium, and potassium.
The Periodic Table of Elements
is a way of organizing all the elements.
Organizing Elements
Elements are organized on the Periodic Table based
on their atomic number and atomic mass.
The atomic number is how many protons
the atom has.
The atomic mass is how many protons and
neutrons the atom has.
Examples of Elements
When you put two or more elements
Hydrogen
and
oxygen

together, you get a new solid, liquid

or gas.
For example, 2 hydrogen atoms
and one oxygen atom make water.
