- Mendeleev used chemical reactivity to determine how to organize the elements of the periodic table into groups and periods. Based on this knowledge, explain why his first table did not include the noble gases. (2 pts) Barrow_forwardThe relative ratio, or percent, of each isotope found in nature is the abundance number used to calculate the average mass. Here's the general equation for average atomic mass: (Abundance A)(Mass A) + (Abundance B)(Mass B) = Atomic Mass For example, here's how the average mass of of boron was calculated. Percent Boron-10 Percent Boron-11 10 + 11 =10.81 amu 100 100 (.20)10 + (.80)11 = 10.8 amu %D 3. Let's try out the atomic mass equation. Suppose you have a mixture of two nitrogen isotopes. For every 1 Nitrogen-15 isotopes, there are 3 Nitrogen-14 isotopes. Determine the abundance of each isotope in this mixture. Predict the average atomic mass of this mixture. Hint: This is NOT the mixture of nitrogen found in nature. You can check your answer by clicking "My Mixture" under isotope mixture.
