The 2s atomic orbital on oxygen is lower in energy compared to the 2p atomic orbital because the 2s orbital experiences greater electron-nucleus attraction due to its spherical shape, which allows the electrons to be closer to the nucleus, resulting in lower energy levels.
Oxygen has a lower first ionization energy compared to nitrogen and fluorine because oxygen has a larger atomic size and a weaker effective nuclear charge, making it easier to remove an electron from an oxygen atom.
Sodium has a larger atomic radius than oxygen. This is because sodium has one more energy level (shell) of electrons compared to oxygen, leading to a greater distance between the nucleus and the outermost electron.
Oxygen has a higher ionization energy than sulfur due to its smaller atomic size and stronger nuclear charge. The electrons in the outer energy level are held more tightly in oxygen compared to sulfur, requiring more energy to remove an electron from an oxygen atom.
The molecular orbital diagram for carbon monoxide shows the overlap of the atomic orbitals of carbon and oxygen to form bonding and antibonding molecular orbitals. The diagram illustrates the energy levels of these orbitals and how they interact to create the CO molecule.
Oxygen has a higher ionization energy than carbon. This is because oxygen has a greater nuclear charge and a smaller atomic size compared to carbon, making it more difficult to remove an electron from an oxygen atom due to stronger attraction between the electrons and the nucleus.

Plants need oxygen for photosynthesis to create energy.
Boron has a larger atomic radius but a smaller atomic mass.
The number of energy shells is increased, S2- (radius 184 pm) the electrons are in 3s2 3p6 whereas in O2- (radius 140 pm) they are 2s2, 2p6. Orbitals of higher principal quantum number project further from the nucleus. The isoelectronic noble gases show the same trend, neon atomic radius 0.88, Argon 1.030)
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
The largest element among boron, carbon, oxygen, and nitrogen is oxygen. It has the highest atomic number and atomic mass compared to the other elements listed.
- Carbon and Oxygen both are on the second period, therefore, they both have two energy shells. - Carbon's atomic number is 6, and Oxygen's atomic number is 8. So Carbon has 6 protons and electrons, and Oxygen has 8 protons and electrons. - Carbon's atomic mass (or mass number) is 12, and Oxygen's atomic mass is 16. - Carbon has 6 neutrons, and Oxygen has 8 neutrons. - Carbon can be black, while Oxygen is clear and odorless.
The ionization energy of phosphorus is higher than that of oxygen because phosphorus has more protons in its nucleus, leading to a greater attraction for its electrons. Additionally, phosphorus has a larger atomic radius compared to oxygen, which results in electrons being further away from the nucleus, requiring more energy to remove them.
