Question

can anybody please tell the valence electron shell by some examples ​

Answer 1

Answer:

For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.

Answer 2

Valence electrons are the electrons located at the outermost shell of an atom.

For example :

1. The oxygen atom, you can see that the outermost shell has 6 electrons, so oxygen has 6 valence electrons.

2. Neon's outermost shell has 8 electrons. Neon therefore has 8 valence electrons.

I hope this will help you.....
