How many protons electrons and neutrons respectively does 29 CS have
irakobra [83]

55 \; \text{e}^{-}, 55 \; \text{p}^{+}, and 74 \; \text{n}^{0}- in case cesium-129 is what you were referring to.

Cesium has atomic number 55 as seen on a modern periodic table. A cesium atom nucleus would thus contain an equal number of protons; in addition to that, a <em>neutral</em> atom of cesium would contain the same number of electrons in its electron cloud.

For a particular isotope,

\text{Mass number} = \text{Number of protons per nuclei} + \text{Number of Neutrons per nuclei}.

This isotope of cesium has a mass number of 129 and contains 55 protons in each atomic nucleus. One cesium nuclei would therefore contain 129 - 55 = 74 neutrons.
