Lesson 1: Structure of the atom
Duration of Days: 4
Lesson Objective
TC* 1.1 - I can describe the structure of the atom, including the location and properties of the subatomic particles
How is matter organized at the atomic level, and how do these arrangements influence the properties of substances?
Atom, proton, neutron, electron, ion, cation, anion, atomic number, mass number, isotope, nucleus, energy level
PS1.A: Structure and Properties of Matter. Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.
DOK 1: Recall
Identify the three subatomic particles and their charges.
Define atomic number and mass number.
Distinguish between protons, neutrons, and electrons.
Label the parts of an atom in a diagram.
Calculate the number of protons, neutrons, and electrons in an atom given its atomic number and mass number.
DOK 2: Skill/Concept
Explain the concept of isotopes and their impact on atomic mass.
Interpret information from the periodic table to determine atomic structure.
Calculate average atomic mass from isotopic abundances.
Predict the electron configuration of elements.
DOK 3: Strategic Thinking
Analyze experimental evidence to support the existence of subatomic particles.
Use quantum mechanics to explain the behavior of electrons in atoms.
