Not sure may I get the answers

To determine the most common isotope of magnesium, we need to find the isotope with the highest natural abundance. The relative atomic mass of magnesium is an average value that takes into account the different isotopes and their relative abundances.

Here are the three isotopes of magnesium and their natural abundances:

1. Magnesium-24: Natural abundance of approximately 78.99%
2. Magnesium-25: Natural abundance of approximately 10.00%
3. Magnesium-26: Natural abundance of approximately 11.01%

Based on these natural abundances, we can see that the isotope with the highest abundance is Magnesium-24, with a natural abundance of approximately 78.99%. Therefore, Magnesium-24 is the most common isotope of magnesium.

To find this information, you can refer to a reliable source such as a chemistry textbook, periodic table, or reputable scientific websites that provide data on the isotopes and their natural abundances.
