Technectium is radio active and therefore it would be a waste just to make a sample of it. Technetium reacts with air, water, halogens, acids, and bases. Technectium is in group 7 so it is in the transition metals family. This element was discovered by Carlo Perrier, Emilio Segre at 1937 in Italy. Technectium comes from the greek word technikos which means artifical.
