In Flourine-19, you can determine that the number of Neutrons is 10.
Now, if you look at Neon-20, you subtract its mass by the number of protons, leaving you with 10.
Therefore, Neon-20 has the same number of neutrons as Flourine-19.
I believe the bond between between F and Cl would be polar covalent.
I believe that this is False.
hope this helps!
