This lesson covers the periodic table, atomic structure, and the Bohr model. Students will learn to determine the number of protons, neutrons, and electrons in elements using the periodic table, identify parts of an atom, and write electron configurations. Key vocabulary includes atomic mass, atomic number, isotopes, and more. The lesson explains atomic structure, including the nucleus, protons, neutrons, and electrons, and how to read the periodic table. It concludes with instructions on drawing Bohr models and understanding electron configurations.

What will you learn by the end of this lesson?

• How to identify different types of chemical bonds.

• How to determine the number of protons, neutrons, and electrons in an element using the periodic table.

• How to create chemical reactions.

• How to measure the weight of an atom using a scale.
