The atom is about 10-10 meters (or 10-8 centimeters) in size. This means a row of 108 (or 100,000,000) atoms would […]
Why ionisation enthalpy of nitrogen is higher than oxygen?
Why ionisation enthalpy of nitrogen is higher than oxygen? An atom is highly stable when its valence orbital is completely filled or half-filled and in nitrogen, the valence p orbital is exactly half filled. So, the ionization energy of nitrogen is more than that of oxygen. What is the first ionization of oxygen? First Ionization […]
