Help!! my teacher ask for atomic notation of: C-12, C-13, S-32, Ar-40, and Fe-56, but l don;t get it.?

Question

Does anybody Knows? Thank's

Answer 1

The form that you want for an atomic notation is: (ignore the .....)

A
....X
Z

where X = symbol of element
A = Mass Number (# of protons)
Z = Atomic Number (#protons + # of neutrons)
p = number of protons = A
n = number of neutrons = A-Z

You just have to figure out what "A" and "Z" is and put it in that form. The first one would be:

6
....C
12

Answer 2

By asking for atomic notation he/she is only asking for you to put the element's symbol alongside its atomic number and atomic mass.
I think your teacher is trying to push the idea of isotopes.

Thanks does not contain an apostrophe
