Define dot structure with appropriate example?

Posted by All In One 4 years, 6 months ago

CBSE > Class 10 > Science

1 answers

Sia ? 4 years, 6 months ago

Lewis dot structures reflect the electronic structures of the elements, including how the electrons are paired. Lewis structures are a useful way to summarize certain information about bonding and may be thought of as “electron bookkeeping”. In Lewis dot structures each dot represents an electron. A pair of dots between chemical symbols for atoms represents a bond.

Lewis Structure of CO₂

The central atom of this molecule is carbon.
Oxygen 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 contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.
