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 ...

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 ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds ... only amino acids capable of forming covalent bonds, which they do with their ...

Substances that consist of covalent molecules are usually gases or liquids at room temperature. Ionic bonds are formed between a metal and non-metal, for example, sodium chloride. Outer electrons ...
