Etymology

Tc is the chemical symbol for technetium, a name from Greek technetos meaning 'artificial' and from techne 'skill' or 'craft', the same root as technology and 'tech'. So technetium is a 'man-made' element often produced in nuclear reactors, which helps explain why it is not found naturally.
