The cesium nucleus has a charge of +55. What is the number of electrons in the Cesium ion? Electron, Neutron, and Proton: The sum of the total number of protons and the number of neutrons is equal to the a...
What is the number of protons and neutrons in it? What is atomic number of the element? What is the number of protons, neutrons, and electrons in a sodium atom? What is the number of protons plus the number of neutrons in the nucleus of an atom equivalent to?...
Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass numbers 114-112 means that cadmium atoms of greater abundance...
The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. A number of artificial radioactive isotopes of cesium are known also. A radioactive isotope is one that breaks apart and gives off some form ...
No matter how many neutrons or electrons it has, an atom with one proton is alwaysatomic number 1and always hydrogen. An atom the contains 6 protons is by definition an atom of carbon. An atom with 55 protons is always cesium. How to Find the Atomic Number ...
