1. Protons:
* Location: Found within the atom's nucleus, a dense, positively charged core at the center of the atom.
* Charge: Positive (+)
* Role:
* Determine the atomic number of an element. The number of protons defines what element an atom is.
* Contribute to the atom's mass.
2. Neutrons:
* Location: Also found within the nucleus alongside protons.
* Charge: Neutral (no charge)
* Role:
* Contribute to the atom's mass.
* Help stabilize the nucleus by counteracting the repulsive forces between protons.
3. Electrons:
* Location: Exist in a cloud of negative charge surrounding the nucleus. They occupy specific energy levels called electron shells or orbitals.
* Charge: Negative (-)
* Role:
* Participate in chemical bonding by forming and breaking bonds with other atoms.
* Determine the atom's chemical properties and reactivity.
Key Points:
* The number of protons and neutrons determines the mass number of an atom.
* Atoms are mostly empty space! The nucleus is incredibly small compared to the overall size of the atom.
* The arrangement of electrons in an atom's shells influences its chemical behavior.
