The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate from them in a manner resembling a real lab.
Through collaborations with individuals and through our many communities, ChemEd DL strives to provide the best of what chemical education has to offer. Teachers and students are encouraged to find, sue, classify, contribute, and evaluate ChemEd DL resources in support of teaching and learning. ChemEd DL resources are classified using a controlled vocabulary of keywords.
The periodic table of the chemical elements displays the organizing principles of matter. The table is a tabular depiction of the chemical elements and their characteristics. Russian chemist Dmitri Mendeleev is generally credited with the invention of the periodic table. The layout of the table has been refined and extended over time, as new elements have been discovered and new theoretical models have been developed to explain chemical behavior.
