An element in a similar period to fluorine would be?
fluorine
What element has properties similar to chlorine and fluorine?
all group 17 atoms are similar, so Bromine and Iodine would also be similar. Astitaine is much less well known but would also be somewhat similar as well.

What atom has 44 neutrons 35 protons and 35 electrons?
The isotope of bromine called 81-bromine. Since the element you are describing has 35 electrons, it must also have 35 protons. Therefore you end up with bromine which is the 35th element (since the amount of protons are equal to the elements number). Adding 46 to 35 gives you the weight of the specific bromine isotope, since the weight of the element is also the name of the isotope. It is also not radioactive.
What is the element with the highest ionization energy?
fluorine bromine chlorine
Which element would have properties most similar to the new element?
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
