The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen. Each redox state of carbon (Fig. 2) is associated with a class ...

In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two ... Nitrogen atoms can form three covalent bonds, so a triple bond forms between them.
