Chlorine is a toxic, corrosive, reactive gas. Which representation (structural formula, electron dot structure, or three-dimensi
DanielleElmas [232]

electron dot structure

Explanation:

Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.

  • The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
  • The chemical symbol represents the nucleus and all electrons except the valence ones.
  • The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
  • Chlorine has 7 valence electrons in its outermost shell.
  • It is made up of 3 lone pairs and 1 odd pair of electron.
  • The odd pair accounts for the reason why chlorine is very reactive.
  • It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.
