Study Notes

Atomic Structure and Properties

  • Protons: These are positively charged particles found in the atom's central nucleus. The number of protons determines the atom's atomic number and thus its identity as a specific element (e.g., all carbon atoms have 6 protons).
  • Neutrons: These particles have no charge (they're neutral) and are also located in the nucleus. They contribute to the atom's mass but don't affect its charge or elemental identity. The number of neutrons can vary within an element, leading to isotopes.
  • Electrons: These are negatively charged particles that orbit the nucleus in specific energy levels or shells. They're much lighter than protons and neutrons. In a neutral atom, the number of electrons equals the number of protons, balancing the positive charge of the nucleus. Electrons are key players in chemical reactions.
