Question

which has more stable configure electronic configuration carbon or oxygen

Answer 1

electronic configuration of oxygen is more stable

hope that helps.....

Answer 2

Hey friend, Harish here.

Here is your answer:

Atomic Number of Carbon = 6.

Electronic Configuration of Carbon is:  2 , 4

Atomic Number of Oxygen = 8

Electronic Configuration of Oxygen = 2, 6

For oxygen to get octet configuration it must gain two electrons.

Whereas for Carbon it must loose or gain 4 electrons to achieve octet configuration. 

So, Oxygen had more stable configuration than carbon .
