It is everything about matter.

1. Matter
An Insight Into The Structure and
Properties of Matter

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.

5. Atoms
Atoms are composed of three types of
particles: protons, neutrons, and
electrons.

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

9. Phases of Matter
 Matter is classified into four phases
or states
 Solid
 Liquid
 Gas
 Plasma

10. Solid
 Solids have definite:
 Mass
 Volume
 Shape

11. Liquid
 Liquids have definite
 Mass
 Volume
 No definite shape.

12. Gas
 Gases have NO definite
 Mass
 Volume
 Shape

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.

14. Review - Phases of Matter
 Gases' shape and
volume is determined
by container.
 Liquids shape is
determined by the
container and has
constant volume.
 Solids have constant
shape and volume.
