Tc has 55 neutrons, its variants such as Tc-99 have a differing number of neutrons ranging from 54, 55, and 56 in the longer lived isotopes such as Tc-99. Tc-99 also has a half-life of 211,000 years.
Technetium has atomic number 43 so has 43 protons. The rest of the mass is neutrons so do 95 takeaway 43.
Technetium-97 has 54 neutrons.
56 neutrons
55* 55 electrons and neutrons.
I don't know Se-55.
55 protons and electrons and 78 neutrons
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
It has 78 neutrons.
Technetium-98 has 55 neutrons.
55* 55 electrons and neutrons.
I don't know Se-55.
55 protons and electrons and 78 neutrons
In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have.
Manganese is a metal element. Atomic mass number of it is 55.
In it's most stable form, 55 is its atomic mass. 55 overall - 25 protons = 30 neutrons
Cesium has an atomic number of 55. Fifty-five indicates the number of protons and electrons. The task here is to find the number of neutrons. To do so, take 134 and subtract 55 to get 79.
Caesium is in the first raw. Atomic number of it is 55. So it has 55 protons.
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
It has 78 neutrons.
Technetium (Tc) has a total of 55 neutrons.
