Draw the structure of oxygen atom.
Oxygen has atomic number 8 and mass number 16. So its atom has
No of protons = 8 No of electrons =8 No of neutrons =(16-8) =8
So 8P and 8n are present in the nucleus. 8 electrons are present outside the nucleus. Out of 8e, two are in the 1st shell (orbit) and 6 are in the 2nd shell (orbit).
No of protons = 8 No of electrons =8 No of neutrons =(16-8) =8So 8P and 8n are present in the nucleus. 8 electrons are present outside the nucleus. Out of 8e, two are in the 1st shell (orbit) and 6 are in the 2nd shell (orbit).
