Question

How would an electron shell model of an oxygen atom (O) appear after the atom has formed chemical bonds? It would have six electrons in the outermost shell.

Answer 1

Answer: It would have 8 electrons in its outermost shell.

Step-by-step explanation:

The outermost shell of an Oxygen atom, usually called valence shells contains only 6 electrons while the rest 2 are in the innermost shell.

When chemicals bonds are formed, it takes in just 2 more electrons from the donor atom to form a stable octet state.

Example is the covalent bond between Hydrogen atom. (Check attatchment)

Answer 2

It would have eight electrons in the outermost shell.

Step-by-step explanation:

This is because O atom would have gained extra two electrons for the chemical bonding (Ionic bond) and hence, the O atom would have eight electrons in the outermost shell (in an octet state).
