Atoms and Ions

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

Provide young chemists with the ability to manipulate atoms and predict their results, in this sixth lesson. Pupils analyze energy patterns as they predict the amount of energy required to remove electrons from atoms. They compare trends...

What a cute approach to chemical bonding! Atoms all have human names and are attending at a dance. Who will pair up with whom? By reading the characteristics, and not the element name, chemistry whizzes figure out the bonding pairs....

Familiarize your new chemists with the periodic table of elements by contemplating this collection of slides. Element groups are identified, atoms are defined, and nuclide notation is explained. Isotopes are also mentioned. The topics...

Sal discusses what happens to elements when they become ionized. He demonstrates that when neutral atoms become ionized, it can significantly change their relative atomic sizes. He uses the Periodic Table of the Elements to illustrate...

Discover the relationship between mass number, atomic number, and the makeup of the atom. The video instructor explains how to determine the number of each subatomic particle from the atomic and mass number. She demonstrates multiple...

Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Here you will find 5 categories regarding atoms, the periodic table, and the elements.  The questions in this jeopardy game are about bonding, ions, oxidation number, and energy levels.
