Bold boxes present parts of the periodic table, with some of the contents conveniently missing. Beginning chemists fill in the blanks, which may include the atomic number, atomic mass, atomic symbol, or element name. Beneath each box...

In this atomic weight and ions worksheet, students answer questions about isotopes of atoms and how it relates to atomic weight. They also write out oxidation or reduction reactions for given atoms undergoing loss or gain of electrons.

For this chemistry worksheet, young scholars determine which compound is the most acidic in each multiple choice question. Then they determine what the major product would be in each of the reactions stated on the sheet.

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

Prepare your chemistry charges for stoichiometry with this PowerPoint. The objective is to be able to calculate molar mass for different compounds. Beginning with the foundational definition of moles and moving through atomic and...

If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

In this chemistry instructional activity, students use the periodic table to complete the chart shown, filling in all of the missing information in the blank spaces. They identify and describe various elements found in the periodic table.
