For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's ...

In this chapter, the origin of life-related molecules is discussed. Life-related molecules are divided into two groups: One group called CHOs consists of molecules made of carbon, hydrogen, and oxygen, such as aldoses, ketoses, and sugars, including ribose. Another group called CHONs is made...
Should life truly exist on an exoplanet, detecting nitrogen as well as oxygen could help astronomers verify the oxygen's biological origin by ruling out certain ways oxygen can be produced abiotically, or through means other than life.

Meanwhile, on the cathode side of the fuel cell, oxygen gas (O2) is being forced through the catalyst, where it forms two oxygen atoms. Each of these atoms has a strong negative charge. This negative charge attracts the two H+ ions through the membrane, where they combine with an oxygen...

To calculate the number ofmoleculesand atoms in a water drop, you need to know the chemical formula of water. There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains 3 atoms. ...
. Crucially, Europa dwells in a region teeming with potent radiation produced by Jupiter's magnetic field. As a result, energized particles (called "ions") pummel Europa's surface. In doing so, these particles split apart the moon's surface water molecules, resulting in hydrogen and oxygen....
