Question
Draw the atomic diagram of the following element showing the distribution of – protons, neutrons and the electrons in the various shell of the atom.
Carbon – \[\ce{^12_6C}\]
[The upper number represent the – mass number and the lower number represent the – atomic number e.g. calcium – mass number = 40, atomic number = 20]
Solution
Carbon – \[\ce{^12_6C}\]
Mass number A = p + n = 12
6 + n = 12
∴ n = 12 − 6 = 6
e = p = Atomic number = 6
C
6 = 2, 4
