Composition of 100 g of carbon steel; element % mass (g) = % mass of steel (g) carbon : 1%: treated alloy steels contain 0.30 to 0.40% C. Carbon has two characteristics that account for its power-ful effects from such small amounts: It is very low in density, so therefore a great number of atoms are present in small amounts (by weight), and its To simulate the 9 at% FeCr alloy, two of the Cr atoms are placed in the two bottommost atomic layers (maximally far from each other). To make Au stronger and harder, it is often alloyed with other metals, such as Cu and Ag. B the answer is the one with Fe as the big molecules and see as a small ones.
