Question

how to calculate valance shell
example what is valance shell of oxygen ? ​

Answer 1

Answer:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

Answer 2

Answer:

Example of Valence Electrons - example

For the oxygen atom, it can be seen that the outermost shell has 6 electrons, so Oxygen has 6 valence electrons. However, Neon's outermost shell has 8 electrons. Hence, Neon has 8 valence electrons.
