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.

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

Electrons are attracted to the protons of other atoms. This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a molecule, creating a polar molecule.

The carbonyl group, characterized by a double bond between a carbon and an oxygen atom, is the central functional unit in organic chemistry. Due to their natural polarity—where the carbon ...

The difference in electronegativity between two bonded atoms determines the bond's polarity, with a large difference indicating a polar covalent bond (e.g., H-F bond) and a small difference indicating ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. "This ...
