Magnesium element has three isotopes: 24mg, 25mg, and 26mg. the natural abundance of the isotopes on earth is 78.99% 24mg with a mass of 23.985 amu, 10.00% 25mg with a mass of 24.985 amu, and 11.01% 26mg with a mass of 25.9825 amu. what is the average atomic mass of magnesium?

24.305 to the nearest thousandth.

Explanation:

That is 0.7899*23.985 + 0.10* 24.985+0.1101*25.9825

= 24.305.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
