Why is caesium's mass number 133?
Caesium is a metal element. Atomic mass of it is 133.
How many protons neutrons electrons does Cs have?
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).
What is the AMU of Barium?
It depends on which isotope you are talking about. Bariuim-133, for instance, has 133 AMU. (Atomic Mass Units) Known isotopes of barium range from -112 to -153.
How many protons neutrons and electrons in the element called neptunium?
93 protons and 93 electrons; the number of neutrons is different for each isotope. For ex.: 144 neutrons in neptunium 237 Tthe number of neutrons is the difference between the atomic mass of an isotope and the atomic number. the sky is pnk
What element Has isotopes of mass 129131132133 and 134?
The element with isotopes of mass 129, 131, 132, 133, and 134 is iodine. These isotopes include both stable and radioactive forms, with iodine-131 being particularly well-known for its medical applications in treating thyroid conditions. Iodine is essential for human health, particularly in the production of thyroid hormones.

Cesium-133 has an atomic number of 55 It has neutrons?
Cesium-133 has an atomic number of 55, which means it has 55 protons in its nucleus. Since the atomic number represents the number of protons, the number of neutrons in an atom of cesium-133 can be calculated by subtracting the atomic number from the atomic mass.
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.
Why is caesium's mass number 133?
Caesium is a metal element. Atomic mass of it is 133.
An atom contains 55 protons and 78 neutrons. Which nuclide symbol is the correct symbol for the atom?
The atom with 55 protons and 78 neutrons is silver-133. Therefore, the correct nuclide symbol would be (_{47}^{133}Ag).
How many protons neutrons electrons does Cs have?
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).
Is xenon radioactve?
Some isotopes of xenon do undergo radioactive decay to caesium.
What is the number of neutrons in a cesium atom?
Cesium (caesium) has the atomic number 55 (55 protons).Virtually all naturally occurring cesium has 78 neutrons (Ce-133).Trace and synthetic isotopes of cesium can have 79, 80, or 82 neutrons.(134Ce, 135Ce, 137Ce)
What is the AMU of Barium?
