The formula is H 2 O so the dot ... Nitrogen molecules consist of two nitrogen atoms joined together. Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen atoms, so the formula of water is H 2 O. A nitrogen molecule is made up of two nitrogen ...

For example, if you've ever drawn a Lewis-dot structure to depict the bonding in a molecule — and you probably have — it is unlikely that representing a covalent ... of nitrogen in the Haber ...
