Atom Structure

Learning Objectives

• Understand the basic structure of an atom including its main components - protons, neutrons, and electrons
• Learn how these particles are arranged within the atom
• Understand the relative sizes and charges of these particles
• Understand the concept of atomic number and its significance

What do you already know about the structure of an atom?

Overview of an Atom

• Atom: The basic unit of a chemical element, consisting of protons, neutrons, and electrons

Subatomic Particles

• Protons: Subatomic particles with a positive charge, located in the nucleus of the atom
• Neutrons: Subatomic particles with no charge, also located in the nucleus
• Electrons: Subatomic particles with a negative charge, orbiting the nucleus in shells

Nucleus

• Nucleus: The dense central part of an atom, containing protons and neutrons

Electron Shells

• Electron Shells: The orbits of electrons around the nucleus, with specific capacities

Relative Size

• Protons and neutrons are much larger than electrons
• Electrons are significantly smaller compared to protons and neutrons

Atomic Number

• Atomic Number: The number of protons in the nucleus of an atom, determining the identity of the element

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.
