How do you calculate average atomic mass? The atomic number for Magnesium, Mg, is 12. The average atomic mass is 24.30 amu. What does this indicate about the number of neutrons?

Learning Intentions

• We will learn how to visualize atomic structure and how parts are related to create the structure.

• We will learn what scientists discovered each part of the atom.

• We will learn how to represent atomic structure in a variety of ways

Closing Task:

You can create a comic strip about atomic structure that includes properties of the parts of an atom, scientists that discovered the parts and how to represent atomic structure.

Content Standards being covered:

Students understand the structure of matter at the atomic level and the history that lead to our current understanding.
