How many neutrons does a cesium 141 have?
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.
What is the mass number of an iron that has 29 neutrons?
The mass number of an iron that has 29 neutrons would be 55. You just take the atomic number of iron, which is 26, and add that to the number of neutrons, which is 29, and you get 55.
How many neutrons does technetium have?
Technetium has 34 isotopes, with no stable isotopes
If technetium-98 has 55 neutrons how many does technetium-99 have?
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.
An atom has a mass number of 25 and 13 neutrons What is the atomic number of this atom?
The element with atomic number 25 is manganese. It has known isotopes with mass numbers including every integer from 49 to 60 inclusive, along with 62. However, the only one that is naturally occurring is the one with mass number 55.
How many neutrons does a cesium 141 have?
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.
How many protons and neutrons does cesium 134 have?
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.
How many neutrons are in an atom of cesium 137?
In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have.
What is the mass number of an iron that has 29 neutrons?
The mass number of an iron that has 29 neutrons would be 55. You just take the atomic number of iron, which is 26, and add that to the number of neutrons, which is 29, and you get 55.
How many neutrons does Manganese-55 have?
Manganese is a metal element. Atomic mass number of it is 55.
How many neutrons does technetium have?
Technetium has 34 isotopes, with no stable isotopes
How many protons electrons and neutrons do Caesium have?
Caesium is in the first raw. Atomic number of it is 55. So it has 55 protons.
What is the mass number of an isotope if it has an atomic number of twenty five?
Manganese or Mn has an atomic number of 25 (25 protons). The stable atom has 30 neutrons, so the stable atomic mass is 55 amu. The mass for one of its isotopes depends on how many neutrons it has. For instance, the next most stable isotope of Mn is Mn53 with only 28 neutrons so it has an atomic mass of 53 amu.
What is the mass of an element?
The mass number of an element is the atomic mass rounded to the nearest whole number. For Example, if the atomic mass is 54.94 (Manganese [Mn]), then the mass number will be 55. You can use the mass number to calculate the amount of neutrons in an isotope.
How many neutrons in Mn-25?
In it's most stable form, 55 is its atomic mass. 55 overall - 25 protons = 30 neutrons
How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and atomic number of 25?
That's Manganese and it has (about) 30 neutrons - - - - BUT your question would have an answer of 11.
If technetium-98 has 55 neutrons how many does technetium-99 have?
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.
