What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic attraction between an atom and the positive ...

Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

Introduce the question students will investigate in this lesson: If atoms have an equal number of protons and electrons, why do atoms bond to other atoms? Why don’t they just stay separate? Begin to ...

The researchers have developed a method to precisely measure the strength of hydrogen bonds in confined water systems, an advance that could transform our understanding of water's role in biology ...
