Matter note chemistry for year 7 & 8.ppt

For year 7 and 8

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
Nodefinite 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.

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.
