In 1940 the chemist Edwin McMillan and the physicist Philip Abelson, both Americans, from the University of California Berkeley, were obtained by the nobel prizes in chemistry, by bombarding Uranium, it is a synthetic element with the symbol Np and atomic number 93, belonging to group of actinides being the fourth of this family and the second in its period, its name comes from the planet Neptune, it is not found in nature in a free state and is reactive, being a solid metal similar to silver, in its most simple, silver and metallic, in the periodic table we find it in group 3 and in the position of period 7.
It has the highest score in its high temperature in liquid state, having magnetic properties it usually eliminates the conductivity of water, but nevertheless it has been shown in recent studies to the contrary, it is highly dangerous because when entering the body it causes fatal damage, it is so powerful that can penetrate paper, gloves, skin, making handling highly dangerous and delicate. Although it is created artificially, it is said to have been on planet earth since its foundation.
Its main use is the fuel of nuclear reactors, of rapid maneuverability and in nuclear weapons, being fissile and extremely useful in these terms of use, in the space and military area it is its only utility in itself, varying in some scientific studies of the chemical and physical, being very dangerous is not used in any other area of human activities.
