* Protons: Located in the nucleus of the atom, protons carry a positive charge. The number of protons defines the element (e.g., carbon has 6 protons).
* Electrons: Orbiting the nucleus in shells or energy levels, electrons carry a negative charge.
* Neutrons: Also located in the nucleus, neutrons have no charge (they are neutral).
Balance is Key:
* The number of protons in an atom determines its atomic number.
* In a neutral atom, the number of electrons precisely matches the number of protons.
* This perfect balance of positive and negative charges results in an overall neutral charge for the atom.
Example:
* A neutral carbon atom has 6 protons and 6 electrons. The 6 positive charges from the protons perfectly cancel out the 6 negative charges from the electrons, making the atom electrically neutral.
Important Note:
* Atoms can gain or lose electrons, becoming ions.
* A cation is a positively charged ion formed when an atom loses electrons.
* An anion is a negatively charged ion formed when an atom gains electrons.
