* Protons: Positively charged particles in the nucleus of an atom.
* Neutrons: Neutrally charged particles in the nucleus of an atom.
* Electrons: Negatively charged particles that orbit the nucleus.
Determining Charge:
* Neutral Atom: In a neutral atom, the number of protons (positive charges) is equal to the number of electrons (negative charges). The positive and negative charges cancel each other out, resulting in a net charge of zero.
* Ions: When an atom gains or loses electrons, it becomes an ion.
* Cation: If an atom loses electrons, it has more protons than electrons, resulting in a positive charge.
* Anion: If an atom gains electrons, it has more electrons than protons, resulting in a negative charge.
What Happens When an Atom Has More Protons Than Neutrons?
* Isotopes: Atoms of the same element can have different numbers of neutrons. These are called isotopes.
* Impact on Charge: The number of neutrons doesn't directly affect the charge of an atom. The charge is determined by the difference between protons and electrons.
Example:
* Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. It's a neutral atom.
* Carbon-14 has 6 protons, 8 neutrons, and 6 electrons. It's also a neutral atom because the number of protons and electrons are equal.
Key takeaway: The charge of an atom is determined by the balance between protons and electrons, not the number of neutrons.
