In this atoms worksheet, students complete a graphic organizer by writing in the number of electrons, valence electrons, electron configuration, orbital box diagram, probability diagram, and Lewis Dot diagram for the given atoms and ions.

For this compounds worksheet, students draw the Lewis dot structure for given compounds plus determine the electron geometry, type of hybrid, molecular geometry, polarity, and number of sigma and pi bonds. This worksheet has 5 fill in...

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

In this electronegativity worksheet, students complete a chart given 10 molecules. They draw their Lewis structures, they draw the shape of the molecule, they determine the difference in electronegativity between the bonds, they...

Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety...

There are two sheets here, with 100 problems total. The first half is a list of compounds, and your young chemists should write the chemical formula for each.  The next fifty give the formula and the name is required.  You...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Explanations of shell structure in an atom and the decisions that affect periodic table organization are discussed here. Students view well organized charts to list and compare elements that are placed in different sections of the...

All different types of bonding are covered in this PowerPoint, along with details of resulting bond and molecule shapes. The definitions of traditional molecule shapes and characteristics of behavior are very useful to assist in...
