Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule ...

Hydrogen atoms are close together. The electron from each atom feels the attraction from the proton in the nucleus of the other atom. This attraction pulls the atoms together and the electrons are ...

A recent collaboration has led to the development of a technique to drastically enhance the performance of perovskite solar cells using hydrogen-bonding additives. This research demonstrates that ...

In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen bonds with cytosine (C). These base pairs are highly ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...
