Question

What is the meaning of Lewis Symbol

Answer 1

Lewis symbols(on the name of an American Scientist G.N.LEWIS) are used to represent number of valence electrons in an atom.

The electrons are represented by small dots around an symbolic atom.

Example:
To represent hydrogen atom's valence electrons, one small black dot is used to show one electron around the nucleus.

This is also known as lewis dot structure
