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?
