- Chemistry-F321
- module 1-atoms and reactions
- moles
- Avogadro constant
- 6.02214179x1023
- Avogadro constant
- titration
- oxidation number
- water of crystallisation
- atomic structure
- atomic masses
- carbon 12 is the standard for measuring atomic masses
- all atomic masses are compared with carbon
- relative molecular mass
- add together the atomic masses in the molecule
- the weight mean mass of a molecule compared with 1/12 of the mass of carbon 12
- protons, neutrons and electrons
- isotopes
- isotopes of the same element have
- different masses
- same number of protons and electrons
- different number of neutrons in the nucleus
- carbon
- the overall charge of the atom must be 0
- mixture of isotopes
- carbon-13
- carbon-12
- carbon-14
- work out the number of neutrons by subtracting the atomic number from the mass number
- different isotopes of the same element react in the same way
- isotopes of the same element have
- isotopes
- atomic masses
- moles
