The isotope symbol that fits each description is as follows: 68 neutrons, 47 electrons is Ag b. mass number = 197, 79 electrons is Au c. atomic number = 86, 136 neutrons is Rn d. atomic number = 76, mass number = 192 is Os.

Isotopes are two or more atom types that share the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a given element are nearly identical, they differ in their atomic weights and physical characteristics.

The name "isotope" refers to the fact that different isotopes of the same element occupy the same location on the periodic table. The word "isotope" is derived from Greek origins that mean "the same place".
