It has 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.
The mass number of an iron is determined by the total number of protons and neutrons. Iron has an atomic number of 26, meaning it has 26 protons. If the iron atom has 29 neutrons, the mass number would be 26 (protons) + 29 (neutrons) = 55.
Technetium has 34 isotopes, with no stable isotopes
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
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.
Cesium (Cs) has 55 protons, as indicated by its atomic number. In a neutral atom, it also has 55 electrons. The number of neutrons can be determined by subtracting the atomic number from the atomic mass; the most common isotope of cesium has approximately 78 neutrons (55 protons + 78 neutrons = 133 atomic mass).
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.
Oh, dude, cesium-134 has 55 protons and around 79 neutrons. It's like the cool kid at the periodic table party, just hanging out with its atomic number of 55 and atomic mass of around 134. So, yeah, it's got its protons and neutrons chillin' like, "What's up, we're cesium-134."
In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have.
The mass number of an iron is determined by the total number of protons and neutrons. Iron has an atomic number of 26, meaning it has 26 protons. If the iron atom has 29 neutrons, the mass number would be 26 (protons) + 29 (neutrons) = 55.
In it's most stable form, 55 is its atomic mass. 55 overall - 25 protons = 30 neutrons
It is an atom of the element manganese (symbol - Mn).
Manganese is a metal element. Atomic mass number of it is 55.
Technetium has 34 isotopes, with no stable isotopes
Caesium is in the first raw. Atomic number of it is 55. So it has 55 protons.
The element with a mass of 55 and 30 neutrons in its atoms is zinc (Zn). This can be determined by subtracting the number of neutrons from the atomic mass of the element.
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
