- Atoms, Isotopes and Compounds
- Mass Number- total nr. of protons and neutrons
- Atomic Number- is the nr. of protons
- The atomic number tells you how many protons there are
- Atoms of the same element all have the same nr. of protons
- Compounds are formed when atoms of two or more elements are chemically combined together.
- For example, carbon dioxide is a compound formed from a chemical reaction between carbon and oxygen
- It's difficult to separate the two original elements out again
- Isotopes are: different atomic forms of the same element, which have the SAME number of PROTONS but a DIFFERENT number of NEUTRONS
