Study Notes
Protons
Definition: Protons are positively charged subatomic particles found in the nucleus of an atom.
Key Characteristics:
- Positive Charge: Protons have a positive charge, which is equal in magnitude to the negative charge of an electron.
- Mass: Protons have a mass of approximately 1 atomic mass unit (amu), which is roughly 1836 times the mass of an electron.
- Stability: Protons are stable particles and do not undergo radioactive decay.
Location in the Atom: Protons are found in the nucleus of an atom, which is the central region of the atom.
Number of Protons:
- The number of protons in an atom's nucleus determines the element of an atom, and each element has a unique number of protons in its atoms.
- The number of protons in an atom is known as the atomic number (Z).
Importance: Protons play a crucial role in the structure and properties of atoms, including:
- Determining the identity of an element
- Influencing the chemical behavior of an element
- Contributing to the overall mass of an atom
