CHEM120 OL, Week 1 Lab
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 numbers
At the end of the simulation, you will be introduced to the quantum mechanical model of
an atom and the four quantum numbers that provide all the necessary information to
describe the orbits of the electrons around the nucleus.
Part 1: Complete Labster Lab Atomic Structure: Assess the possibility of life on
other planets
