1st Define Covalent bond and it's type
irakobra [83]

Answer:

  1. COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
  • SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
  • DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
  • TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms

2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

3))Sulfur has an atomic number is 16 with the

symbol as 'S'

  • The electronic configuration of sulfur is said to be 2,8,6
  • The valence electrons present in sulfur is 6.
  • Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
  • The sulfur molecule's chemical formula is S8.
  • Sulfur is usually used in the manufacture of sulphuric acid.
