Question

Draw the electron-dot structure of Carbon dioxide and Sulphur molecule which is made
up of eight atoms of Sulphur.

Answer 1

Answer:

The atomic number (Z) for carbon is six and its electronic configuration is 2, 4. Carbon has four valence electrons. Each oxygen atom (Z = 8) has six valence electrons (2, 6). In order to complete its octet, the carbon atom shares its four valence electrons with the four electrons of the two oxygen atoms as follows :

Thus, in carbon dioxide molecule, the carbon atom is linked to two oxygen atoms on both sides by two shared pairs of electrons resulting in double bonds on either sides. Both carbon and oxygen atoms complete their octet as a result of electron sharing

Answer 2

What would be the electron dot structure of a molecule of sulphur which is made up of eight atoms of sulphur ? (Hint: The eight atoms of sulphur are joined together in the form of a ring) Answer: The atomic number (Z) of sulphur is sixteen and its electronic configuration is 2, 8, 6.
