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.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

In this radon and radioactivity worksheet, learners analyze the data of the isotopes of elements that occur in the decay series of uranium-238. Students answer 6 questions about the isotopes, their half-lives, their potential threat and...

In this half-life instructional activity, students are given a particular mass of an isotope of cesium and its half life. They are to determine how much cesium will remain after 90 years. They are guided through the problem solving process.

In this nuclear chemistry worksheet, students answer ten questions about radioactive decay, half life, electron capture and alpha emission.

In this 9th grade science review worksheet, students complete 63 true or false questions on topics such as atomic notation, isotopes, covalent bonds, Ohm's law, and electric circuits.
