Study Notes
Internal Structure of an Atom
- Atoms comprise three primary subatomic particles: electrons, protons, and neutrons.
Charge Characteristics
- Electrons carry a negative charge of -1.
- Protons possess a positive charge of +1.
- Neutrons have no charge, which is represented as 0.
Mass Characteristics
- The actual mass of an electron is approximately 9.109 x 10^-28 grams.
- The actual mass of a proton is around 1.673 x 10^-24 grams.
- The actual mass of a neutron is roughly 1.675 x 10^-24 grams.
Relative Mass
- The relative mass of an electron is defined as 1 unit.
- In comparison, a proton has a relative mass of 1837 units, making it significantly heavier than an electron.
- A neutron has a similar relative mass to the proton at 1839 units, indicating that both protons and neutrons are much more massive than electrons.
