A Correct answer
Explanation

Mendeleev’s Periodic table says that the periodic function of their relative atomic masses. Mendeleev arranged all the 63 elements in it. These only were discovered in his time. These are in the order of their increasing relative atomic masses in a tabular form. It is the Periodic Table. He had the table with eight columns and seven rows. The columns are the groups whereas rows are the periods.

Hence, the correct option is A.

C Correct answer
Explanation

After the rejection of Newlands Octave Law, Mendeleev Periodic table came into existence. In Mendeleev’s periodic table, elements were placed based on the atomic mass, and chemical properties. During Mendeleev’s work, only 63 elements were found. After studying the properties of all elements, he found that the properties of elements were related to atomic mass.

Hence, the correct option is C.

B Correct answer
Explanation

In 1869, Dmitri Mendeleev and Lothar Meyer individually came up with their own periodic law "when the elements are arranged in order of increasing atomic mass, certain sets of properties recur periodically." 


Hence, the correct option is $\text{B}$

Two elements were elected by Mendeleev for studying the properties of compounds formed by other elements with the selected elements. What were the selected elements?

  1. Oxygen, Nitrogen

  2. Hydrogen, Carbon

  3. Hydrogen, Oxygen

  4. Oxygen, Carbon

C Correct answer
Explanation

The elements selected by Mendeleev were oxygen and hydrogen because most of the elements reacted with oxygen and hydrogen.
