An atom has an atomic number of 56 yet has a mass number of 137 amu evalution of data indicates that the element is?
barium
How many particles make up a barium?
its atomic number is 56 its atomic weight is 137 hope that helps
What is the mass number for cesium?
The standard atomic weight for cesium is 133. There are 3 other radioactive cesium isotopes that have atomic weights of 134, 135, and 137. Cesium 133 is the only one that is found in nature. The other isotopes are synthetic.
How many neutrons are in the nucleus of an atom of 118 50 Sn?
Sn (tin) has an atomic number of 50, which indicates there are 50 protons in its nucleus. If the atomic mass is 118, then the number of neutrons is the difference between the two numbers, or 68 neutrons.

What is the weight of cesium?
Ceasium is a metal element. Atomic mass of it is 133.
What is the atomic mass number in barium?
The mass number is the sum of protons and electrons in the atomic nucleus of an isotope. Barium has many isotopes and each has another mass number.
What is the atomic number and atomic mass number of barium?
The atomic number of barium is 56. It has naturally occurring isotopes with mass numbers of 130, 132, 134, 135, 136, 137, and 138.
How many protons electron neutrons and nucleons in a barium atom?
Proton = 1 Neutron = 1 Electron = 0.00054
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 nuclear reaction for the transformation of Cs-137 into Ba-137?
Beta Emission as there is no change in the atomic mass of the atom but there is an increase in the atomic no. of the atom.
What is the mass of a barium atom?
The mass of a barium atom is approximately 137 atomic mass units (u).
What is the parent radioisotope if a beta decay produces barium 137?
Same mass, atomic number one lower - Cs - caesium
