- How is the mass number related to the number of protons and neutrons an atom has?arrow_forwardWhat particles are found in the nucleus of an atom? What is the charge of the nucleus?arrow_forwardThough the common isotope of aluminum has a mass number of 27, isotopes of aluminum have been isolated (or prepared in nuclear reactors) with mass numbers of 24, 25, 26, 28, 29, and 30. How many neutrons are present in each of these isotopes? Why are they all considered aluminum atoms, even though they differ greatly in mass? Write the atomic symbol for each isotope.arrow_forward
- Calculating Atomic Mass Magnesium has three naturally occurring isotopes with masses 23.99,24.99,and25.98amu and natural abundances 78.99,10.00,and11.01%. Calculate the atomic mass of magnesium.arrow_forwardHow do isotopes of a given element differ? How are they similar?arrow_forward2.19 Naturally occurring uranium consists of two isotopes, whose masses and abundances are shown below: Only 235U can be used as fuel in a nuclear reactor, so uramium for use in the nuclear industry must be enriched in this isotope. If a sample of enriched uranium has an atomic weight of 235.684 amu, what percentage of 235LT is present?arrow_forward
- While traveling to a distant universe, you discover the hypothetical element X. You obtain a representative sample of the element and discover that it is made up of two isotopes, X-23 and X-25. To help your science team calculate the atomic weight of the substance, you send the following drawing of your sample with your report. In the report, you also inform the science team that the brown atoms are X-23, which have an isotopic mass of 23.02 amu, and the green atoms are X-25, which have an isotopic mass of 25.147 amu. What is the atomic weight of element X?arrow_forwardHow is an atom’s atomic number related to its number ofprotons? To its number of electrons?arrow_forwardThe isotope of plutonium used for nuclear fission is 239Pu . Determine (a) the ratio of the number of neutrons in a 239Pu nucleus to the number of protons, and (b) the number of electrons in a single plutonium atom.arrow_forward
