II. Isotopes Atoms of a given element all have the same number of protons and electrons, but can have different numbers of neutrons. Versions of the same element with differing numbers of neutrons are call isotopes. The symbol for an isotope is AX Where: A is the mass number (number of protons plus neutrons) Z is the atomic number (number of protons) X is the symbol for the element 2. Show the isotope symbol for the isotope of Fe with...
2) Calculate the number of electrons contained in a small electrically neutral pin made of silver, with a mass of 15.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g / mol. (b) Suppose that electrons are added to the pin until the net negative charge equals 5.5 mC. How many electrons need to be added for every 109 electrons already present?
