CHEM 120Week 1 Labster - Atomic Structure - Part II

Week 1 Labster - Atomic Structure - Part II OL Lab 2: Atomic Structure: Assess the possibility of life on other planets Learning Objectives • Explain the concept of an atom • Explain the properties of the basic subatomic particles: protons, neutrons, and electrons • Define the atomic number and atomic mass • Define isotopes • Identify the basics of the quantum atomic model and describe the significance of the four quantum numbers Atoms and the subatomic particles Everything you see around you is made up of atoms, and all atoms consist of subatomic particles. In the Atomic Structure simulation, you will learn the names and properties of the basic subatomic particles and understand how changing the number of electrons may charge an atom either positively or negatively. Identify different elements from the periodic table As a part of your mission, you will be teleported to an exoplanet to explore on your own, collect samples and come up with observations regarding the presence of life on the planet. Back in the laboratory, you will investigate the properties of the elements you brought back from the exoplanet. The periodic table will be close by to advise and guide you. What is an isotope? In order to understand the main properties of an isotope in the Atomic Structure simulation, you will use the holo-table. With the holo-table, you will be able to see a magnified atom of Lithium, and you will get the chance to build different isotopes of the same element. The quantum model and quantum num
