What's the Matter? Locating Electrons in an Atom

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...

Lead the class on an investigation as they play detective and locate patterns in the electron arrangement of atoms. During the seventh lesson, they assign valence numbers to elements, organize the periodic table in the correct sequence,...

Connect the dots and assist young chemists as they demonstrate covalent and ionic bonding. Class members use their knowledge of valence electrons to predict compound formulas as they arrange electrons into various bonding structures to...

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

In this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each and...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

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...

Learn about an electron's negative charge, location, and role in bonding. Website also investigates electrons uses in electricity.
