2.8 Atomic Mass: The Average Mass of an Element's Atoms ..

Atoms—and the protons, neutrons, and electrons that compose them—are extremely small. For example, a carbon atom weighs less than 2 10 −23 g, and an electron has a charge of less than 2 10 −19 C (coulomb). When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu) and the fundamental unit of charge (e) An atom's mass number is the number of protons in an element. An atom's mass number is not found on the periodic table because it is determined by counting the protons and neutrons in a specific isotope of the element. Because it is a counted value, the mass number does not have any units. Video: The Periodic Table What does the periodic table tell us about each element 45 neutrons. Click to see full answer. Simply so, how many neutrons are in bromine 79? Bromine (Br), at atomic number 35, has a greater variety of isotopes. The atomic mass of bromine (Br) is 79.90. There are two main isotopes at 79 and 81, which average out to the 79.90amu value. The 79 has 44 neutrons and the 81 has 46 neutrons It's not possible to have different elements with same number of protons. Each element has got particular number of protons. Each element can have different number of neutrons. They are called as isotopes
