plz explain with example

answered-by-expert Expert Answer
Valence electrons are present in an atom of an element.

The electrons present in the outermost shell or valence shell are known as valence electrons.

The number of electrons donated or accepted or shared by its atom during a chemical reaction is called valence electrons, and the number of these electrons is called the valency of that element.

Using the valency of ions, we can write the formulae of compounds.
