boron family project
indium
Indium is used to make mirrors that are as reflective as silver mirrors but do not tarnish as quickly
Indium is used in nuclear medicine tests, as a radio tracer to follow the movement of labeled proteins and white blood cells in the body.
Indium is used to dope germanium to make transistors. It is also used to make other electrical components such as rectifiers, thermistors and photo conductors.
thallium
Thallium is poisonous and highly toxic it was used for rats poisoning
Thallium it is used for infrared detectors
Thallium used for torture because it is slow working and painfull
