How many protons neutrons and electrons make up beryllium?
WebIron-54 is composed of 26 protons, 28 neutrons, and 26 electrons. Iron-56 is composed of 26 protons, 30 neutrons, and 26 electrons. Iron-57 is composed of 26 protons, 31 neutrons, and 26 electrons. Iron-58 is composed of 26 protons, 32 neutrons, and 26 electrons. Iron-56 is the most stable nucleus. WebAtoms are grouped according to the number of protons and neutrons in the atomic nucleus. The number of protons in an atom determines the chemical element of the atom, and the number of neutrons determines isotope of that element. A stable atom is an atom in which all of its orbitals are occupied by electrons so that none of the orbitals are vacant. Web17. how many protons and neutrons are present is an atom of calcium (mass#=40)? Answer: The mass number of an isotope is the sum of the number of protons and neutrons in the atomic nucleus. The atomic number is the number of protons. The calcium-40 isotope has a mass number of 40 , and an atomic number of 20 , therefore it has 20 protons ... chinese food buffalo rd rochester ny
