Question

1. Make a claim that answers the following question: "What is the

connection between the number of valence electrons and
chemical/physical properties?" *

Answer 1

Lets take an example to explain this

Sodium(Na) has 1 electron in its outer or valence shell hence it will lose it and become a cation say to Chlorine(Cl)

To form Sodium Chloride.

Since it is capable of losing electrons, Sodium becoems a metal and has properties of metal

Whereas Chlorine which has 7 electrons in its valence shell gains an electrons to become an anion

Hence it is a non metal

And has the properties of an anion
