Mass Number
The total number of protons and neutrons.
1 of 5
Atomic Number
The number of protons.- Atoms of the same element all have the same number of protons-- so atoms of different elements will have different numbers of protons.
2 of 5
What do you do to get the number of neutrons?
- Just subtract the atomic number from the mass number. Electrons aren't counted in the mass number because their relative mass is very small.
3 of 5
What are the masses of the particles?
Proton- 1 Neutron- 1 electron- very small
4 of 5
What are compounds?
- Compounds are formed when atoms of two or more elements are chemically combined together. for e.g, carbon dioxide is a compound
