How do valence electrons affect how atoms bond?

Answer 1

if atom has enough valence electrons to all pair up like noble gases do they are resistant to change and are not able to bond with any other atom however if there are not enough valence electrons to all pair up the unpaired electrons are unstable and are able to bond with other atoms to share their electrons.

Answer 2

To help the particle such as chlorine which has 7 valence electrons in the outermost shell to obtain a stable octet structure, which has 8 valence electrons to become stable and less reactive, the valence electron will undergo covalent bonding to bond with another chlorine atom to obtain a chlorine molecule that is stable and less reactive.

Answer 3

Depending on the valency of an element, that determines the amount of bonds it can form. E.g oxygen has a valency of two and carbon a valency of four, therefore, oxygen can form one bond with 2 carbon atoms and another 1 bond with another 2 carbon atoms = Carbon Dioxide. (VALENCY= HOW MANY BONDS IT CAN FORM)...p.s refer to the LEWIS STRUCTURE!!

Answer 4

The number of valent electrons an atom has, predicts its ablility to form bonds.
