Answer 2

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Examples of covalent compounds include:

• O2 – oxygen.
• Cl2 – chlorine.
• PCl3 – phosphorus trichloride.
• CH3CH2OH – ethanol.
• O3 – ozone.
• H2 – hydrogen.
• H2O – water.
• HCl – hydrogen chloride.
