- Atomic Structure
- Middle of Atom
- Small Nucleus
- Contains 2 types of particles - Protons and Neutrons.
- Small Nucleus
- Protons
- Positive charge (+1)
- No of protons in each atomic called its atomic number
- Elements in the periodic table are arranged in order of atomic number
- Neutrons
- No Charge (0)
- Because Atom has equal numbers of Protons and Neutrons - the charge evens out to create no charge.
- No of neutrons + protons = Mass number
- So if a atom has 4 protons and 8 neutrons it's mass no will be 12.
- No Charge (0)
- Middle of Atom
