Why is f smaller than o2

Ingenhousz discovered that plants, while exposed to light, give off bubbles from their leaves but while not exposed to light, the bubbles are not produced. The gas in the bubbles was oxygen. He also discovered that plants deprived of light give off carbon dioxide. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius. As the effective nuclear charge which holds the electron of a atom increases the radius of an atom decreases as it is tightly pulled towards the nucleus of atom.

So Al has more effective nuclear charge than Mg. Because N3- has only 7 protons and F- has 9, smaller attraction exerted by the nucleus on the e- results in a larger N3- ion. Whereas, Cl- is larger than Cl because it has gained an extra electron and so, the no.

Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus. The difference, however, should be quite small. Even though both ions are isoelectronic, there is a greater nuclear positive charge in the oxide ion causing its electrons to be more tightly pulled toward the nucleus. However, O2- has 8 protons and N3- only has 7. The pull of the electrons by the protons in the nucleus is stronger in O2- because there are more of them, so the ion is pulled tighter and smaller.

F-ion is smaller when compared with O2-ion because of the larger nucleus charge of the F-ion. Therefore, in all the given ions it is common that all of them have 10 electrons. This leads to inter-electronic repulsion and thus increases the atomic radius slightly. The atomic radii of nitrogen is larger than oxygen. The greater the value of PPM, the bigger the atomic radii. Each oxygen atom has 8 protons in its nucleus, while each nitrogen atom has only 7 protons in its nucleus.

Thus, the overall size of the electron cloud of the O2 molecule is smaller than for N2, in part because its electron cloud is drawn in closer to the O nuclei by the greater positive charge on the O nuclei. Due to strong electronegativity 3. The size of any element depends on the atomic radius of the element. And, the periodic table is arranged also according to the atomic radius of the elements. The actual masses of individual oxygen atoms are not whole numbers even though their mass numbers are whole numbers.

When protons and neutrons combine to form the oxygen nucleus, a very small amount of the total mass is converted to nuclear binding energy….
