Atoms of eight elements A, B, C, D, E, F, G, and H have the same number of electron shells but different number of electrons in their outermost shells. It was found that elements A and G combine to form an ionic compound. This ionic compound is added in a small amount to almost all vegetables and dishes during cooking. Oxides of elements A and B are basic in nature while those of elements E and F are acidic. The oxide of element D is, however, almost neutral. Based on the above information, answer the following questions:(a) To which group or period of the periodic table do these elements belong?(b) What would be the nature of compound formed by a combination of elements B and F?(c) Which two of these elements could definitely be metals?(d) Which one of the eight elements is most likely to be found in gaseous state at room temperature?(e) If the number of electrons in the outermost shell of elements C and G be 3 and 7 respectively, write the formula of the compound formed by the combination of C and G.
