2. What Is Matter?
Matter is anything that has mass
and volume.
A cup, pen, and eraser are made up
of matter
3. What Is Matter?
The definition of matter is often
taken to mean anything composed
of atoms and molecules.
Thus, matter is anything made of
protons, neutrons, and electrons.
4. Structure Of Matter
The atom is the “building block of
matter”.
All substances are composed of
invisible particles called atoms.
Atoms are the building blocks of
matter and are in constant motion.
The combination of atoms leads to
millions of materials with different
properties.
6. Nucleus
Atoms are made up of a positively charged center,
the nucleus, containing:
- Protons with a positive charge
- Neutrons with no charge (neutral)

7. Atom
The electrons of an atom are found
orbiting the nucleus of the atom
Electrons have a negative charge
13. Plasma
Plasma is the form of matter that
exists when the atoms are in an
excited state.
Stars (the sun is a star) exist in the
plasma state because of nuclear
fusion.
Some examples of plasma found on
Earth are: lightning, auroras, and
neon.
15. Review - Phases of Matter
Gases' shape is
determined by
container and volume
is determined by
container.
Liquids shape is
determined by the
container and has
constant volume.
Solids have constant
shape and volume.
