Fluorine's atomic radius is smaller than that of oxygen and larger than that of chlorine. This is due to fluorine having more protons than oxygen, which increases the effective nuclear charge and pulls the electrons closer to the nucleus, resulting in a smaller radius. Conversely, chlorine has more electron shells than fluorine, leading to a larger atomic radius. Thus, the order of atomic radius is: chlorine > fluorine > oxygen.

What is oxygens atomic mass?

Oxygens Atomic Mass is 16.0


How do the atomic number of the different isotopes an element compare?

The atomic number is the same for the all isotopes of a chemical element.


How does it's atomic radius compare to that of krypton?

The element krypton's atomic radius is 189 pm. This is a measurement of its atom sizes or the distance between the electron cloud and the nucleus.


What is the definition of atomic mass number?

Atomic Mass is the sum of the number of protons and neutrons in the atom, plus any additional mass conferred by electrons. (Since electrons are roughly 1/1837th of a proton's mass, this additional mass is minuscule and is only represented in atoms that have atomic numbers at the higher end of the table.) It should be an integer/whole number.The reason that most elements have a number with decimals for their atomic mass numbers on the Periodic Table is because those numbers average all of the different isotopes of the element in proportion to how common they are. For example, Oxygen has an atomic mass number of 15.999 since the overwhelming majority of oxygens have 8 protons and 8 neutrons for a total atomic mass number of 16, but there are some rare oxygens with 8 protons and 7 neutrons for a total atomic mass number of 15. Once these are averaged, since the 16s are much more common, the resulting number is 15.999.
