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.
it would have six electrons in the innermost shell.
it would have eight electrons in the outermost shell.
it would have eight electrons in the innermost shell.

Option (c) is the correct answer.

Explanation:

Atomic number of oxygen atom is 8 and its shells contain 2, 6 electrons. This means there are 6 electrons in the outermost shell.

So, in order to complete its octet, oxygen atom requires 2 more electrons. Therefore, it will readily accept two electrons from an electron rich atom.

Hence, then there will be eight electrons in the outermost shell of an oxygen atom (O) after the atom has formed chemical bonds.
