    In the first image, an oxygen atom is shown with six valence electrons. Four of these valence electrons form pairs at the top and right sides of the valence shell. The other two electrons are alone on the bottom and left sides. A hydrogen atom sits next to each the lone electron of the oxygen. Each hydrogen has only one valence electron. An arrow indicates that a reaction takes place. After the reaction, in the second image, each unpaired electron in the oxygen joins an electron from one of the hydrogen atoms so that the valence rings are now connected together. The bond that forms between oxygen and hydrogen can also be represented by a dash.

    Figure 2.9 (OpenStax, Biology 2e) caption: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds it forms a water molecule.

  • Molecules and Light

    • Simulation
    Screenshot: Phet Simulation - Molecules and Light.  Various options of Microwave, Infrared, Visible and ultra violet light sources.  Options to choose Carbon Monoxide, Nitrogen, Oxygen, Carbon Dioxide, Water Nitrogen or Ozone, with buttons to start pause the simulation and to show the light spectrum.

    Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

  • Geometric illustration of atoms. Caption: So here we've drawn in all the atoms.

    Molecules form when individual atoms create bonds by sharing electrons. Understanding how atoms combine to make molecules allows scientists to predict many of the physical and chemical properties of substances. Since the outermost eight electrons are key to forming compounds, this unit shows how the Octet Rule provides a basis for predicting how atoms may gain, lose, or share electrons to fill the slots in their outer shells. A fundamental understanding of how electrons form bonds leads to the three-dimensional shapes of molecules and has implications in all aspects of chemistry. Part of the series Chemistry: Challenges And Solutions.

  • Gloved hand holding an electronic chip with a pair of tweezers. Caption: they call it an artificial leaf.

    To manipulate chemical reactions on a large scale, scientists use stoichiometry to quantify those reactions. The use of stoichiometry ensures there are the right amount of reactants and products. Without it, reactions can be incomplete, with expensive materials wasted and harmful byproducts created. Using stoichiometry, scientists are creating chemicals that take the place of petroleum in fabricating sustainable materials. At a different lab, scientists are mimicking the process of photosynthesis to convert the sun’s energy into storable chemical energy. Part of Chemistry: Challenges and Solutions Series.

  • Illustration of human body. Caption: Enzymes, antibodies, even our muscles are all protein based.

    With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.

    Carboxyl groups, which consist of a carbon with a double bonded oxygen and an upper O upper H group attached to a carbon chain, are able to ionize, releasing H positive ions into solution. Carboxyl groups are considered acidic. Sulfhydryl is a polar molecule.

    Figure 2.27 (OpenStax, Biology 2e) caption: These functional groups are in many different biological molecules. R, also known as R-group, is an abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule.

  • Two moles strapped together pulling in opposite directions while a bird in a cage is balancing on their backs. Mass-mass Mole-mass. Caption: to figure out mass, find out how reactants work together,

    Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
