Study Notes
Protons, Neutrons, and Electrons
- Protons are found in the nucleus of an atom.
- Electrons occupy areas around the nucleus in orbits.
- Neutrons are also located in the nucleus alongside protons.
- Neutrons carry no electric charge (neutral).
- Electrons have a charge of -1 (negative charge).
- Protons possess a charge of +1 (positive charge).
- Atoms are composed of protons, neutrons, and electrons.
- Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu).
- Electrons have a significantly smaller mass of about 1/300 amu.
- AMU stands for atomic mass unit, a standard unit of mass in atomic and molecular physics.
- Electrons are the smallest among protons, neutrons, and electrons.
- Isotopes are variants of elements that have the same number of protons but different numbers of neutrons.
- An element consists of only one type of atom.
- Compounds are formed when different elements chemically combine.
- Molecules consist of non-metallic elements that are chemically bonded.
- The mass number of an atom is the total count of protons and neutrons in its nucleus.
- The atomic number indicates the total number of protons within an atom's nucleus.
