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.

∙ 15y agoCesium has 55 protons, this in turn will always be the Atomic Number of Cesium. The isotope Cesium-133 has 55 protons plus 78 neutrons. The number of neutrons varies creating different isotopes of Cesium most of which have short half-lives. The half life measures the stability of an isotope. After a certain amount of time, the number of particles inside atoms increases or decreases, as the atom splits or fuses with other atoms. At this time energy is released. Radioactivity is the result of atoms splitting or fusing and releasing energy. This energy is measured in electron volts (eV), or thousand electron volts (KeV), million electron volts (MeV).

If this isn't right or u need more help ask some one else
SCIENCE ROCKS! ;D

An atom with 55 protons and 76 neutrons?
This atom would be a specific isotope of cesium, with an atomic number of 55. Its mass number, which is the sum of protons and neutrons (55 + 76), would be 131.
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.
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 electrons could a Cesium CS ion have?
A Cesium CS ion is formed when a Cesium atom loses one electron. Therefore, a Cesium ion (Cs+) will have 55 electrons, as opposed to the neutral Cesium atom which has 56 electrons.
What is the sum of protons and neutrons in an atom?
Mass number!:)
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.
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.
An atom with 55 protons and 76 neutrons?
This atom would be a specific isotope of cesium, with an atomic number of 55. Its mass number, which is the sum of protons and neutrons (55 + 76), would be 131.
What is the symbol of an isotope of cesium whose atoms have 82 neutrons?
You are looking for the symbol of cesium (Cs) and indication of its mass number. The mass number is the sum of the protons and neutrons. So if every atom of cesium has 55 protons, then the mass number of this isotope is 137. The mass number is indicated in superscript before the symbol: 137Cs
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 electrons could a Cesium CS ion have?
A Cesium CS ion is formed when a Cesium atom loses one electron. Therefore, a Cesium ion (Cs+) will have 55 electrons, as opposed to the neutral Cesium atom which has 56 electrons.
How many neutrons are in one atom?
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.
How many neutrons are in Cesium (Cs)?
How many neutrons are in Cesium-130 (Cs)?
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 protons and neutrons and electron does caesium have?
Cesium has 55 protons. The non-ionic form has 55 electrons. The number of neutrons, however, varies depending on which isotope you are talking about. The stable isotope 133Cs has 78 neutrons. The most commonly used unstable isotope 137Cs has 82 neutrons. There are isotopes of cesium ranging all the way from 112Cs at 57 neutrons to 151Cs at 96 neutrons.
