Learning Goal: Atoms with the same number of protons but different numbers of neutrons are called isotopes. Some elements only have one naturally occurring isotope, while others such as carbon have two or more. In a naturally occurring sampl Isotopes of each element are present in a certain percentage amount called the percent natural abundance. The mass number of an isotope is the sum of the number of protons and the number of neutrons for a particular isotope and is symbolized by A. A = number of protons + number of neutrons There are several different types of isotope notation. For example, a carbon isotope that has an atomic number of 6 and a mass number of 13 could be symbolized in any of the following ways: C, carbon-13, or C-13. Part A . Enter the appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation 4X. Express your answer as a chemical symbol using Isotope notation. View Available Hint(s) ΑΣΦ 4 ?

4. Let's try another atomic mass problem. Suppose you have a mixture of two chlorine isotopes. The mixture is 40% Chlorine-37 and 60% Chlorine-35. Predict the atomic mass of this mixture. Hint: This is NOT nature's abundance of chlorine. You can check your answer by clicking "My Mixture" under isotope mixture. Next, create the mixture described in the problem. 35.8 amu 36.2 amu 36.0 amu
