Why can certain things only be turned into certain other things? For example, if you mixed flour, sugar, eggs, and other ingredients, you will not make gold. You will not make rubber, or diamond, or straw either. Why not? In the following space, explain why someone cannot make gold by mixing flour, sugar, and eggs.

You cannot make gold with bakery ingredients as gold is made with hydrogen and helium. Not everything follows the same recipe as some objects. There are different recipes for each material which makes sense because minerals aren't made of wheat. Those minerals feel like stone and act like stone, so it wouldn't be logical if it was crafted with flour, sugar and eggs.

Hope this helps.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
