radiation to Nickel-60 and also releases strong gamma radiation. This gamma radiation can only be effectively stopped with several centimetres of lead and so has no problem passing straight through metal equipment in order to sterilise it. As the gamma rays travel through the equipment‚ they kill any living creature such as bacteria or viruses. With a reasonably long half-life of over five years‚ it is a good choice of equipment for sterilisation as it will give off strong gamma radiation without needing

Technetium has an atomic number is 43 so it has 43 protons and 55 neutrons. On periodic table‚ it’s located on Group 7‚ Period 5‚ and Block d. It has an atomic mass of 98. According to Aufbau Principle and Hund’s rule the full electron configuration of Technetium is 1s22s22p63s23d104s24p64d55s2 and condensed electron configuration of Technetium is [Kr] 4d55s2. First Ionization energy of Tc is 702 kJ mol 1 and second Ionization energy is always higher so it is 1470 kJ mol 1. (Winter‚ M) Technetium

The house programed to read a poem that is called ‘There will come Soft Rains” and

Radioactive Isotopes Radioactive isotopes are any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays. Every chemical element has one or more radioactive isotopes. More than 1‚000 radioactive isotopes of the various elements are known.. Approximately 50 of the isotopes are found in nature; the rest are produced artificially as the direct products of

Ray Bradbury satirized this very
