Because of his failure with New Coke, Coca-Cola Classic was born. Without the first failure, there would not have been the great success of the new campaign. You see, God can turn your failures into ultimate success. He can turn your test into a testimony; your mess into a message.
Gamma decay occurs when the nucleus undergoes an energy state change without actually changing the number or ratio of nucleons. . Technetium-99m (99mTc) is an example of such an atom. Its nucleus is the isomer of Technetium-99 (99Tc), and as an isomer, Technetium-99m rests at a higher energy state than the ground state Technetium-99.
Alpha Decay is a radioactive decay in which a nucleus splits by emission of alpha particle. The nucleus loses its 2 neutrons and 2 protons hence its mass number decreases by 4 and atomic number decreases by 2.
