Draw the electron dot diagram of Hydronium ion. H = 1 ; O = 8

A water molecule contains two hydrogen atoms and one oxygen atom. A hydronium ion is formed when the lone pair of electrons on oxygen atom in water molecule bonds with a hydrogen ion.

Draw the electron dot structure of Ammonium ion. [ N = 7 , H = 1 ]

Electronic configuration of nitrogen is 2 , 5 and that of hydrogen is 1 . Nitrogen has 5 valence electrons. In ammonia, there are three nitrogen-hydrogen single bonds and a lone pair on the nitrogen atom. When it reacts with H + ion, the lone pair is used to form a coordinate bond between the nitrogen atom and hydrogen ion. The electron dot structure of ammonium ion is:

Draw the electron dot structure of Sodium chloride. [ Na = 11 , Cl = 17 ]

Electronic configuration of sodium is 2 , 8 , 1 and that of chlorine is 2 , 8 , 7 . Sodium loses its one valence electron to chlorine forming a positive ion and chlorine gains one electron forming a negative ion. These ions form an electrovalent bond. The electron dot structure of sodium chloride is:

Draw the electron dot structure of Nitrogen. [ N = 7 ]

Nitrogen has 5 valence electrons, and it will share three valence electrons with another nitrogen atom to form a triple covalent bond. Therefore, the electron dot structure of nitrogen is:

Give the appropriate term defined by the statement given below: The covalent bond in which the electrons are shared equally between the combining atoms.

The covalent bond in which the electrons are shared equally between the combining atoms is non-polar covalent bond. The covalent bond is also termed as nonpolar because the difference in electronegativity is mostly negligible. A non-polar covalent bond can occur between two identical non-metal atoms or between different atoms.
