Usually overuse by repetitive movements of the sinus tarsi from over pronation or an ankle sprain that is inverted are the two (2) reasons causing this area of pain. Both cause irritation and traumatic injury to the tissues that are located in the sinus tarsi.
Answer   Hydrogen is composed of one proton and one electron.   Some isotopes of hydrogen are slightly different. Deuterium contains one proton, one neutron, an â¦ d one electron. Tritium contains one proton, two neutrons, and one electron.
Hydrogen has three isotopes (triplets): hydrogen-1 (protium), hydrogen-2 (deuterium) and hydrogen-3 (tritium). In the illustration below, we can see subscripts and superscripts. The superscripts 1, 2 and 3 written before H are the atomic masses of the isotopes of hydrogen and the subscript 1 is the atomic number.ritium (hydrogen-3), has an atomic mass of 3.0160492, and it consists of one proton and two neutrons. Its nucleus is triple the mass of protium. What distinguishes tritium from protium and deuterium is that it is radioactive, which means that its nucleus is unstable so its nucleus decays and emits radiation.
