The formula is H 2 O so the dot and cross diagram includes ... Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The structure of nitrogen is N≡N, showing ...

Use the diagram on page 130 Teaching Secondary Chemistry which summarised how different macroscopic structures relfect different ways of bonding atomic cores together with valence electrons.

The dot and cross diagram shows that ... Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The structure of nitrogen is N≡N, showing that it has three shared ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds ... This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a ...
