Activity 3. The AT:M Family Objectives: 1. Describe the atom and its subatomic particles. 2. Draw an atom and label its parts. Direction: Part 1. Read the basic information about the atom and answer the questions that follow. The term "atom" came from a Greek word "atomos" meaning "indivisible". Today, an atom is defined as the smallest particle that makes up matter. For decades, scientists have been gathering evidence about its structure. Their studies led to the conclusion that atoms are mostly empty space and they have three major subatomic particles. First, the electrons, the negative part of the atom, travel in random paths around its central part known as the nucleus. The nucleus contains the second and third parts, the proton and neutron. The protons and neutrons are both small but massive and their masses are nearly equal. The proton is positively charged, while the neutron has no charge. Protons and neutrons contribute to the mass of the atom. Protons and neutrons are called nucleons because they are found inside the nucleus. The table below shows some of the properties of the three subatomic particles. Subatomic Charge Mass, grams Location in the atom Particle (symbol) Electrons (e') Protons (p) Neutrons (nº) Negative Positive 9.109 X 10 •28 Outside the nucleus 1.672 X 10 -24 Inside the nucleus zero 1.675 X 10 24 Inside the nucleus Guide Questions: 1. What is an atom? 2-4. What are the three major subatomic particles of the atom and their charges? 5. Which subatomic particle is the lightest? 6. Which subatomic particle has no charge? 7. Where can you find the electrons? 8. What is the collective term for protons and neutrons? PART 2. Draw an atom with 2 protons, 2 electrons and 2 neutrons inside the box. Color and label its parts.
