Calculate the specific energy of a scandium atom.

Scandium is located in the fourth period of the III group of the secondary (B) subgroup of the Periodic Table.

The scandium atom consists of a positively charged nucleus (+21), inside which there are 21 protons and 24 neutrons, and around 21 electrons move in four orbits.

The outer energy level of the scandium atom contains 3 electrons, which are valence. The oxidation state of scandium is +3.

∆m = (Nmn + Zmp) – My

∆m = (24 1.007276 + 21 1.008665) – 44.95591 = (24.17 + 21.18) – 44.95 = 45.35 – 44.95 = 0.4

E = ∆mc2

E = 0.4 9 1016 = 3.6 10 ^ 16J
