The element cesium (Cs) has an atomic number of 55, which means it has 55 protons in its nucleus, regardless of the isotope. The isotope 133Cs specifically indicates that it has 133 nucleons (protons + neutrons), but the number of protons remains the same at 55. Therefore, 133Cs contains 55 protons.

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.

4+ because however much more protons there are then that is the charge
Protons and neutrons account for almost all the mass of an atom. Electrons have much less mass compared to protons and neutrons.
The atomic mass is made up of protons and neutrons in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. Electrons, which have a negative charge, are not included in the atomic mass as they are much lighter than protons and neutrons.
35 protons
scandium has 21 protons!
Chlorine has 17 protons.
36 Protons. Check the Atomic Number, because it stands for the number of Protons.
60 protons, as its atomic number is 60.
Boron has 5 protons in its nucleus.
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
Protons and neutrons have about the same mass, but electrons are much, much lighter.
Lithium, regardless of its atomic mass, has 3 protons.
no. protons and neutrons are MUCH larger than electrons.
The atomic number of xenon is 54. So there are 54 protons in xenon.
Yes.
