Lesson: Quarks Chemistry

In this lesson, we will learn how to describe the properties of quarks and the composition of protons and neutrons.

Lesson Plan

Students will be able to

explain that protons and neutrons are made from subatomic particles known as quarks,
name the six flavors of quark and the electrical charge associated with each,
describe the composition of neutrons and protons in terms of the number of and types of quark,
explain how the electrical charges of neutrons and protons result from the specific combination of quarks.

Q1:

A composite particle is composed of 2 up quarks and 1 down quark. What is the overall electric charge of this particle?

Q2:

Which of the following denotes the two values of electrical charge a quark can have?

Q3:

What electrical charge does an up quark possess?
