Answer

Atom; strong nuclear, electromagnetic, weak nuclear, gravitational; protons, neutrons, electrons; F = k \frac{|q_1 q_2|}{r^2}; atom is the building block of matter. Explanation 1. Identify the smallest unit of an element The smallest unit of an element is the atom. 2. List the four fundamental forces from strongest to weakest Strong nuclear force, electromagnetic force, weak nuclear force, gravitational force. 3. Define subatomic particles Subatomic particles are particles smaller than atoms (protons, neutrons, electrons). 4. State Coulomb's Law **Coulomb's Law:** F = k \frac{|q_1 q_2|}{r^2}, where F is force, k is Coulomb's constant, q_1 and q_2 are charges, r is distance. 5. Define atom An atom is the basic unit of matter, consisting of a nucleus (protons and neutrons) and electrons.
