A Review Constants 1 Periodic Table Subm Previous Answers Correct When identifying isotopes of an atom, we look for atoms that have the same number of protons but different masses. This means that each isotope has a different number of neutrons. In an atomic symbol of an isotope, the upper left number represents the mass number (which consists of the sum of protons and neutrons in the nucleus of the atom) and the lower left number is...

-Isotopes are represented by the symbol , where Z is the atomic number, A is the mass number, and E is the elemental symbol. . Write symbol that represents an isotope of nickel that contains 28 protons and 32 neutrons in the nucleus. Isotopes are also represented by the notation: Name-A, where Name is the name of the of the isotope. An example of this isotope notation is magnesium-26. This represents an isotope of The extremely small size of atoms...
