• made up of tiny particles called atoms 2. Atoms have spaces between them. 3. Heating atoms gives them energy & makes them move faster. 4. Atoms are always moving.
What are the 3 different types of atoms called?
• Neutrons 2. protons 3. electrons.
Describe neutrons
they have no charge. found at the centre of the atom
describe protons
they have a positive (+) charge Found at the centre of the atom
Describe Electrons
Have a negative (-) charge found moving around the outside of the atom
if there are more protons then what does the particle of matter have?
positive charge
if there are equal protons and electrons then what does the particle matter have?
Neutral charge (no charge)
if there are more electrons then what does the particle matter have?
Negative Charge.
