Atoms &
Elements
- STRUCTURE
- protons, +, RAM1
- neutrons, 0 charge, RAM 1
- electrons, -, RAM 0
- number of electrons = number of protons
- Nucleon number= number of proton + number of neutron
- Proton number = number of proton =number of electron
- protons, +, RAM1
- ISOTOPES
- Same element, different number or neutrons
- AVERAGE RAM =(% x mass of first isotope)+ (% x mass of second isotope)
- RADIOISOTOPES
- Radioactive: break down or decay over time,
giving out radiation
- Used to kill cancer cells
- Used as medical tracers
- Used to detect leaks in oil and gas pipes
- Used to sterilize things
- Radioactive: break down or decay over time,
giving out radiation
- Same element, different number or neutrons
- PERIODIC TABLE
- arranged in order of proton number
- rows are periods, columns are groups
- period number shows number of shells
- group number shows valency electrons
- valency electrons dictate how an element reacts
- arranged in order of proton number
