Question

the electronic configuration of oxygen is 2,6 and that of carbon is 2,4.how many electrons in the outer shell of an oxygen atom are involved in the formation of carbon dioxide molecule?

Answer 1

Answer:

Oxygen will share 4 electrons of its outer most shell in order to form the molecule of Carbon Dioxide.

Explanation:

Since the given elements are non - metals that is oxygen and carbon. They will form ionic bond.

Electronic configuration of :

Oxygen = k, L = 2,6

Carbon = k, L = 2,4

Here, the electrons in outer most shell or valence electrons of :

Oxygen = 6

Carbon = 4

Here, in order to form ionic bond, carbon will share its 2 electrons to oxygen to complete the octet that is complete the outer most shell with 8 electrons of oxygen and help it to attain its noble gas configuration of argon.

And, oxygen will share its 4 electrons to help carbon in order to complete its octet and attain the noble gas configuration of argon.
