How many protons does cesium have? How many protons are in a radium-226 nuclide? How many protons (p) and neutrons (n) are in an atom of barium-130? How many neutrons does manganese have? If an atom has an atomic number of 8, how many protons will it have?
Because the protons all have the same charge and would naturally repel one another, the neutrons act as "glue" to hold the protons tightly together in the nucleus. Behave, Atom The number of protons in the nucleus determines the behavior of an atom. For example, if you combine 13 protons...
In the neutral, non-charged state, every atom has the same number ofelectronsas it does protons. Elements starting with helium also contain a number ofneutronssimilar to and usually slightly in excess of the proton number. Variants of elements with different numbers of neutrons are called isotope...
