Question

Definition of Valence Shell

Answer 1

Answer:

The electrons that occupy the outer most shell of an atom are called valence electrons. They are important because they determine how an atom will react. By writing an electron configuration, You'll be able to see how many electrons occupy the highest energy level.

the oxygen atom, you can see that the outermost shell has 6 electrons, so oxygen has 6 valence electrons. Neon's outermost shell has 8 electrons. Neon therefore has 8 valence electrons

Answer 2

Answer:

valence shell is that type of shell which we used to valence
