Atoms of seven elements M, N, O, P, Q, R and S have different numbers of electronic shells but have the same number of electrons in their valence shells. The elements M and O combine with chlorine to give an acid and common salt respectively. The oxide of element M is liquid at room temperature and is neutral while the oxides of remaining six elements are basic. Now, answer the given questions:
What could the element M be?
Will elements M to S belong to the same period or same group of the periodic table?
Mention the formula of the compound formed by reacting the element M with oxygen.
Explain the formation of the compound by combining element O with chlorine using electronic structure.
What would be the ration of number of combining atoms in a compound formed by combining element M with carbon?
Which one of the given elements has the smallest atomic radius?

Answer:
M = hydrogen
O=sodium
Explanation:
When M combined with chlorine:
(1):
M+cl-acid
So it is hydrogen
H+cl-hcl(acid)
(2):
When O combined with cl(chlorine):
O+cl2-common salt
So it is sodium
2Na+cl2-2nacl
(3):
Yes,the elements m to s belonging to alkali metal (first group).
(4): the ratio of m to carbon means ch4(methane) so ratio of hydrogen and carbon is 4:1
(5): hydrogen having smallest radii.

Answer:
The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt, NaCl: The word salt is a general term that applies to the products of all such acid-base reactions.
