It is true that atomic radius decreases across the period however, neon being an inert gas experiences more repulsion between the the different shells of electrons thus increases the size so much that it is even bigger than the first element in the period.

Does fluorine share more characteristics with bromine or neon How can you tell?
Fluorine and bromine have 7 valence electrons and hence their properties are similar. Neon has 8 valence electrons and the properties are different from that of fluorine.
Is N larger in size or F?
In terms of atomic radius yes, nitrogen is larger than fluorine. However, the common fluorine isotopes have a greater mass than those of nitrogen.
Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
How does the ionization energy of Ne compare to that of Se?
Neon is a much smaller atom than selenium because neon has fewer occupied energy levels so it has a considerably smaller atomic radius. For that reason, it will be more difficult to remove an electron from Ne than Se, so Ne has the greater ionization energy.
Is fluorine denser than water?
No. Fluorine is a gas at room temperature a little bit denser than air.
Helium and neon cant form compounds with fluorine why?
The first Ionization energy of fluorine is less than that of the helium and neon.
Is N larger in size or F?
In terms of atomic radius yes, nitrogen is larger than fluorine. However, the common fluorine isotopes have a greater mass than those of nitrogen.
Does fluorine share more characteristics with bromine or neon How can you tell?
Fluorine and bromine have 7 valence electrons and hence their properties are similar. Neon has 8 valence electrons and the properties are different from that of fluorine.
Which has a greater electron affinity fluorine or bromine?
Fluorine has greater electron affinity than bromine, or any other element.
Why oxygen forms positive charge with fluorine?
Because fluorine has greater electronegativity than oxygen.
Does oxygen have a greater mass than neon?
No
Why does O2 has greater ability to stabilize higher oxidation states than F2?
The size of oxygen is bigger than fluorine therefore has the ability to stabilized higher oxidation state.
Why does Helium has higher IP than Neon?
because the size of helium is smaller than that of neon.
Why chlorine is highly reactive than other halogens?
It isn't. Fluorine is more reactive. However, Chlorine is more reactive than Bromine, Iodine and Astatine. It is all to do with molecular size. Fluorine wants to get to a stable 10 electrons to be like Neon more than Chlorine wants to get to get 18 lectrons to be like Argon. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and thus more strongly attracted.
Is the electronegativity of fluorine more than that of hydrogen?
Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).
Why does fluorine has higher ionization energy than neon?
because neon is a noble gas which has stable electronic configuration ,but this is not the same in case of fluorine.This means we have to give high energy to gaseous neon atom to ionise it.
Why fluorine is stronger oxidising agent than chlorine?
Oxidising agents gain electrons. Fluorine is a smaller atom than chlorine, so the effective pull of its nucleus is greater.
