Atoms of eight elements A, B, C, D, E, F, G and H have the same number of electronic shells but different number of electrons in their outermost shell. It was found that elements A and G combine to form an ionic compound which can also be extracted from sea water. This compound is added in a small amount to almost all vegetable dishes during cooking. Oxides of elements A and B are basic in nature while those of E and F are acidic. The oxide of D is almost neutral. Based on the above information, answer the following questions:(i) To which group or period of the periodic table do the listed elements belong? (ii) What would be the nature of compounds formed by a combination of elements B and F?(iii) Which two of these elements could definitely be metals and which are likely to be non-metals?(iv) Which one of the eight elements is most likely to be found in gaseous state at room temperature?(v) 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.(vi) Which one of the eight elements is likely to be a noble gas?(vii) Which one of the eight elements would have the largest atomic radius?(viii) Which one of these eight elements is likely to he a semi-metal or metalloid?
