What is the natural percent abundance of the heavier isotope of gallium?

The natural percent abundance of the heavier isotope of gallium, gallium-71, is approximately 39.892%.


Calculate the average atomic mass of copper-63 and copper-65?

The average atomic mass of copper is 63.55 g/mol. This value is calculated by taking a weighted average of the masses of copper-63 and copper-65, based on their natural abundances in a sample of copper. Copper-63 has a natural abundance of 69.17%, while copper-65 has an abundance of 30.83%. Calculating the average atomic mass would involve multiplying the atomic mass of each isotope by its natural abundance, and then summing the results.


What is the abundance in nature?

Abundance in nature refers to the relative prevalence of a species or element within an ecosystem. It describes how common or rare a particular species or resource is compared to others in a given environment. Abundance can be influenced by various factors such as competition, predation, habitat suitability, and environmental conditions.


Why do elements which exists as isotopes have fractional atomic mass?

Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
