Study Notes
Subatomic Particles
- The charge of a proton is positive.
Atomic Structure
- Most of the mass of an atom is found in the nucleus.
Electron, Proton, and Neutron
- The mass of an electron is significantly smaller compared to a proton or neutron.
- A neutron has no charge.
Electron Cloud
- The electron cloud accounts for the region around the nucleus where electrons are likely to be found.
Neutral Atoms
- When an atom is in a neutral state, it has an equal number of protons and electrons.
Ions
- When an atom gains or loses electrons, its net charge changes.
- A negative net charge indicates an excess of electrons.
- A positive net charge indicates a deficiency of electrons.
- Ions are atoms that have gained or lost electrons, resulting in a net charge.
Elements
- The differences in the number of protons, neutrons, and electrons account for the unique properties of each atom.
- The number of protons in an atom's nucleus identifies the atoms of a specific element.
