Flowchart - history of atomic structure models

This folder contains experiments from the Curriki repository. In many cases, teacher notes and answer keys are not included, and will require some preparation on the teacher's part.

This folder contains resources for a project in which students make a 3-D chart of a periodic property across the periodic table. Properties may include melting point, boiling point, density, atomic radius, etc. This resource is part of the Chemistry course which contains units on Lab Setup and Safety; Nomenclature; Chemical Reactions and Balancing; Metric Systems & Conversions; Periodic Table and Trends; Atomic Structure; Nuclear Chemistry; Acids, Bases, & Salts; Bonding; Percent Composition; Solutions, Molarity, and Concentrations; Stoichiometry; Energy; Gas Laws; Reaction Rates and Equilibrium; Electron Configuration; and Redox Reactions.

This resource is a PowerPoint presentation on atomic theory. It covers history from Democritus to Dalton, subatomic particles, atomic mass, atomic number, ions, and isotopes.

This resource is a PowerPoint presentation to be given early in a chemistry class. This particular version is meant to review concepts of atomic structure already learned the previous year.

This resource is a PowerPoint presentation on the periodic table: periods, groups, history, electron configurations, octet rule, energy levels, periodic trends, shielding effect, ionization energy, electron affinity, etc. There are 54 slides in this presentation.

This unit includes resources, such as slideshows, worksheets, activities, and labs, on Nomenclature (chemical names, formulas, etc) for high school chemistry students. This resource is part of the Chemistry course which contains units on Lab Setup and Safety; Nomenclature; Chemical Reactions and Balancing; Metric Systems & Conversions; Periodic Table and Trends; Atomic Structure; Nuclear Chemistry; Acids, Bases, & Salts; Bonding; Percent Composition; Solutions, Molarity, and Concentrations; Stoichiometry; Energy; Gas Laws; Reaction Rates and Equilibrium; Electron Configuration; and Redox Reactions.

In this lab, a shapecylinder, triangular prism, etcis hidden under a piece of plywood. Students roll marbles at it, make observations, and try to describe the shape. They then compare and contrast with the experiment where Rutherford fired alpha particles at a sheet of gold foil.

This resource is a worksheet on periodic trends: atomic radius, ionization energy, electron affinity, electronegativity. It includes an answer key and explanations.

This resource is a blank periodic table, arranged to emphasize families/groups.

Edible Atom Project

This worksheet covers finding the number of atoms in compounds.

This lab deals with the activity series of metals. Objectives include: 1) Observe the reactivity of common metals. 2) Be able to predict the products of a single replacement reaction between a metal and an acid. 3) Be able to write and balance equations for these reactions.
