Subatomic Particles and Atomic Number
Students will identify protons, neutrons, and electrons, and relate their numbers to atomic number, mass number, and elemental identity.
Key Questions
- Explain how the number of protons uniquely identifies an element.
- Compare the properties and locations of protons, neutrons, and electrons within an atom.
- Analyze the role of subatomic particles in determining an atom's overall charge.
