What is the significance of valence electrons?

Expert Answer
Significance of valence electrons:
- The valence electrons of an atom are responsible for and take part in chemical change.
- The valance electrons determine the combining capacity or the valency of the atom. The number of electrons in atom that actually take part in a chemical reaction is known as the valency of the element.
- If the outermost shell of an atom is completely filed, its valency = 0
- Elements having the same number of valence electrons in their atoms possess similar chemical properties.
- Element having different number of valence electrons in their atom show different chemical properties.

ANSWERED BY EXPERTCBSE 9 - Chemistry
. Then i have to first react Carbon with Oxygen then react that compond with calcium. So how will i know the valency of compound formed from reaction of carbon with oxygen. We can know the valency of elements from their atomic number and electronic configuration, but how can i know the valency of compound?
Please help,waiting for your reply,
Thank you. Asked by hk.sachdev | 12 Oct, 2018, 10:38: PM
