Copper atoms and zinc atoms get melted together to form brass. Both atoms have similar atomic radius (135 pm). Based on that information, which of the following diagrams best represents the structure of this alloy and why?

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

It is 4.92 e-4 sorry if i am wrong

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck
