Question

ques.....Atoms of seven elements A, B, C, D, E, F and G have a different number of
electronic shells but have the same number of electrons in their outermost shells
The elements A and C combine with chlorine to form an acid and common salt
respectively. The oxide of element A is liquid at room temperature and is a
neutral substance, while the oxides of the remaining six elements are basic in
nature. Based on the above information answer the following questions:
(a) What could the element A be?
(6) Will elements A to G belong to the same period or same group of the periodic
table?
(C) Write the formula of the compound formed by the reaction of the element A
with oxygen.
(d) Show the formation of the compound formed by a combination of element
C with chlorine with the help of electronic structure.
(e) What would be the ratio of number of combining atoms in a compound
formed by the combination of element A with carbon?
W Which one of the given elements is likely to have the smallest atomic radius?​

Answer 1
