- Chemistry - Atomic Structure
- Isotopes
- Loosing electrons = Positive atoms
- Different amount of neutrons as element
- Gain electrons = Negative atoms
- Same amount of protons as element
- How to calculate relative atomic mass from percentages
- 2) Add these together
- Divide the total by 100
- 1) Multiply percentage by mass of element in compund
- Reactant ---> Products
- Determining Reaction Equations
- 3) Balance the equation
- 2) Add state symbols
- 4) CHECK EVERYTHING BALANCES AGAIN
- 1) Find formula and add charges on ions
