The corresponding matches are 20, 39, 19, 8, and 2
i am sorry i am not sure mabey ask dude for help
Thank you for trying. :)

@dude
number of protons is always in the left corner
atomic mass is under the element
So the number of protons is 19. the atomic mass is 39
yes
atomic mass = Protons + Neutrons protons = 19 39 = 19 + ??
20
20 Neutrons
so that's neutrons?
we sent at the same time lol
the 4 set of numbers on the right side correspond to the Shells so the first number is the 1 shell and the third is the 3 shell
the first shell is 2 and the second shell is 8
yep
crap it asked for the 3rd shell not second, good thing they're both the same XD. Thank you pixel!
