Answer 3

how did you get that?

Answer 4

Find the element on the periodic table and the big number you see is the amount of protons it has. Now that number is also the amount of electrons it has and so you minus the amount of protons it has from the 112 giving you the number of neutrons. p + n = 112.

Answer 6

wow, nevermind lol. also its iodine so its 53 would that be the protons and then subtract 127 by 53 for the neutrons?
