promethium उदाहरण वाक्य
उदाहरण वाक्य
- Research at Laboratori Nazionali del Gran Sasso showed that europium-151 experimentally decays to promethium-147 with the half-life of 5 years.
- Lighter unstable isotopes of samarium primarily decay by electron capture to isotopes of promethium, while heavier ones convert through beta decay to isotopes of europium.
- Note : element 43 ( Tc ) Technetium and element 61 ( Pm ) Promethium are missing from the graph due to their extremely low abundance.
- Lighter unstable isotopes of samarium primarily decay by electron capture to isotopes of promethium, while heavier ones decay by beta decay to isotopes of europium.
- The isotopes of promethium range in atomic weight from 125.95752 u ( 126 Pm ) to 162.95368 u ( 163 Pm ).
- Elements with atomic numbers 1 through 40 are all stable, while those with atomic numbers 41 through 82 ( except technetium and promethium ) are metastable.
- In atomic batteries, the beta particles emitted by promethium-147 are converted into electric current by sandwiching a small promethium source between two semiconductor plates.
- In atomic batteries, the beta particles emitted by promethium-147 are converted into electric current by sandwiching a small promethium source between two semiconductor plates.
- Note that there are two breaks where the unstable elements technetium ( atomic number : 43 ) and promethium ( atomic number : 61 ) would be.
- :: : : The promethium article notes that there is probably about 570 g that exist in the earth's crust at any one time.
