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 – $${\phantom{A}}_{\phantom{6}}^{\phantom{12}}{\phantom{A}}_{\phantom{2}6}^{\phantom{2}12}\mathrm{C}$$

[The upper number represent the – mass number and the lower number represent the – atomic number e.g. calcium – mass number = 40, atomic number = 20]

Answer 1

Carbon – $${\phantom{A}}_{\phantom{6}}^{\phantom{12}}{\phantom{A}}_{\phantom{2}6}^{\phantom{2}12}\mathrm{C}$$
Mass number A = p + n = 12
6 + n = 12
∴ n = 12 − 6 = 6
e = p = Atomic number = 6
                      C
6 = 2, 4
      (K, L)
