- Atomic structure
- Atom
- No overall charge
- Protons
- In the nucleus
- Relative mass 1
- Charge +1
- Neutrons
- In the nucleus
- Relative mass 1
- Charge 0
- Provide a glue to hold the nucleus together despite electrostatic repulsion between protons and electrons
- Electrons
- Arranged in shells
- Relative mass 1/1836
- Charge -1
- Every atom of an element has the same number of protons
- Isotope
- Atoms of the same element with different numbers of neutrons and different masses
- Have the same chemical reactions as their electron structure and number does not change
- physical properties such as boiling point and density may vary slightly due to the change in mass
- Ion
- Charged atom
- Cation- positive ion, fewer electrons than protons
- Anion- negative ion, more electrons than protons
- Has a different number of electrons
- Charged atom
- Cation- positive ion, fewer electrons than protons
- Anion- negative ion, more electrons than protons
- Charged atom
