The Structure of Atoms

Slide 1 - Tekstslide

Slide 2 - Video

The three possible particles in an atom
Protons: give the atom its atomic number, the atomic number is the amount of protons, a proton is positively charged.

Neutrons, these together with the amount of protons give the atomic mass. A neutron has no charge

Electrons: are flying around the core in orbitals, are the same amount as the protons and are negatively charged.

Slide 4 - Tekstslide

Isotopes
Each element has an atomic number = number of protons.
Each atom has a mass number = number of protons + neutrons.
The number of neutrons can differ.
Then we have the same element (type of atom)
but with different mass numbers.
We call these isotopes.
