Storyboard Text
- Slide: 1
- PROTON
- The proton is found in the NUCLEUS of the atom. It has a relative charge of +1 and a relative mass of 1 amu.
- Slide: 2
- NEUTRON
- The neutron is found in the NUCLEUS of the atom. It has a relative charge of 0 and a relative mass of 1 amu.
- Slide: 3
- ELECTRON
- The electron is found outside the NUCLEUS of the atom. It has a relative charge of -1 and a relative mass of ~0 amu.
- Slide: 4
- ATOMIC NUMBER
- The atomic number is 3.
- The atomic number tells us the number of PROTONS in an atom. Since atoms have no charge, it also tells us the number of ELECTRONS in an atom.
- Slide: 5
- MASS NUMBER
- The mass number is the sum of PROTONS + NEUTRONS in the atom. Since protons and neutrons each have a mass of 1 amu, their sum is the same as the mass.

- What are the atomic number and mass number of this atom?
- Slide: 0
- The mass number is 7. 3 + 4 = 7
