WebSolution For The nuclei of common isotopes of hydrogen, helium, lithium and beryllium are shown. Which nucleus contains equal numbers of up and down q The world’s only ... Since the number of protons and the number of neutrons is same in the helium atom, therefore the number of up and down quarks is equal in the helium nucleus. Hence the ... WebAtoms—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 …
