Exploring the World of Atoms

Learning Objective

Understand the basic structure of an atom and its components.

What do you already know about atoms?

What is an Atom?

Atoms are the basic building blocks of matter, composed of protons, neutrons, and electrons.

Parts of an Atom

Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus in energy levels.

Protons

Protons have a positive charge and determine the element's identity.

Neutrons

Neutrons have no charge and contribute to the stability of the atom.

Electrons

Electrons have a negative charge and are involved in chemical bonding and reactions.

Atomic Number and Mass Number

The atomic number is the number of protons in an atom, while the mass number is the sum of protons and neutrons.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
