4. Atomic TerminologyAnswer and explain with a sentence or two:(a) What are the atomic number and the atomic mass number of a fluorine atom with 9 proton and 10 neutrons? If we could add a proton to this fluorine nucleus, would the result still be fluorine? What if we add a neutron to the fluorine nucleus?(b) The most common isotope of gold has atomic number 79 and atomic mass number of 197. How many protons and neutrons does the gold nucleus contain? If the isotope is electrically neutral, how many electrons does it have? If it is triply ionized, how many electrons does it have?(c) Uranium has atomic number 92, Its most common isotope is 238U, but the form used in nuclear bombs and nuclear power plants is 235U. How many neutrons are in each of these of uranium?
