Mendeleev's system was more elaborate than that of Lohar Meyer because he used a broader range of___________to classify the elements.

A

physiological properties

B

physical properties

C

physical and chemical properties

D

chemical properties

Text Solution

Verified by Experts

The correct Answer is:
C
In particular, Mendeleev relied o the similarities in the empirical formulas and properties of the compounds formed by the elements. Lothar Meyer had developed a table of the elements that closely resembles the modern periodic table. However, his work was not published until after the work of Dmitri Mendeleev.

Read the passage and answer the following questions. Mendeleev was a Russian chemist, who contributed the most for the development of periodic table of elements wherein the elements were arranged on the basis of their fundamental property, the atomic mass and also on the similarity of chemical properties. Only 63 elements were known at his time. He arranged the 63 elements in the increasing order of the.ir atomic masses and found that there was a periodic recurrence of elements with similar physical and chemical properties. He observed that elements with similar properties fall in the same vertical column. These vertical columns are called groups and horizontal rows of elements are called periods. Mendeleev predicted the existence of certain elements not known at that time and named two of them as Eka-silicon and Eka-aluminium. Classify these elements as metals, non-metals and metalloids.

How do we classify these newly discovered elements (eka-aluminium and eka-silicon)?

Answer question numbers 3(a) - 3(d) on the basis of your understanding of the following paragraph and the related studied concepts: Around the year 1800, only 30 elements were known. Dobereiner in 1817 and Newlands in 1866 tried to arrange the then known elements and framed laws which were rejected by the scientists. Even after the ejection of the proposed laws, many scientists continued to search for a pattern that correlated the properties of elements with their atomic masses. The main credit for classifying elements goes to Mendeleev for his most important contribution to the early development of a Periodic table of elements wherein he arranged the elements on the basis of their fundamental property, the atomic mass and also on the similarity of chemical properties. The formula of their hydrides and oxides were treated as basic criteria for the classification of the elements. However, Mendeleev's classification also had some limitations as it could not assign the position to isotopes. He also left some gaps in the periodic table. 3(a) state Mendeleev's Periodic Law. 3(b) Why did Mendeleev leave some gaps in the Periodic table? 3(c) if the letter 'R' was used to represent any of the elements in the group , then the hydride and oxide of carbon would respectively be represented as (i) RH_4 , RO (ii) RH_4 , RO_2 (iii) RH_2 , RO_2 (iv) RH_2 , RO 3(d) isotopes are (i) atoms of an element with similar chemical properties but different atomic masses. (ii) atoms of different elements with similar chemical properties but different atomic masses. (iii) atoms of an element with different chemical properties but same atomic masses. (iv) atoms of different elements with different chemical properties but same atomic masses.
