WebNitrogen’s position in the periodic table ( group 15) reveals that it is a nonmetal. Nonmetals form negative ions (anions). A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−. WebThe ratios are the same for each sample, therefore these results are consistent with the law of constant composition. A compound composed of two elements A and B has a ratio of Mass A/Mass B = 3.0. Decomposition of the compound produces 9.0 g of element A. What is the mass of element B. Mass A/Mass B = 3.0.
