Answer:
The relationship of pH and concentration of H+ ion is pH = -lg[H+]. So the concentration of H+ is 10^(-2). And [OH-][H+]=10^(-14). pOH + pH = 14. So the right answer is A.
Atomic Radius: Br
Ionization Energy: Sc (not sure about this one, couldn’t find it in the periodic table)
Electronegativity: N
Reason: Found electronegativity and atomic radius in my periodic table, wasn’t sure about ionization energy, so i hope i guessed right
