NEET Chemistry Periodic Table Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Dmitri Mendeleev | (i) Periodic Law |
| (b) Lothar Meyer | (ii) Increasing atomic weights |
| (c) Semi-metals | (iii) Characteristic properties |
| (d) Alkali metals | (iv) Covalent compounds |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
Dmitri Mendeleev is credited with the Periodic Law, which states that properties of elements are periodic functions of their atomic weights. Lothar Meyer also worked on a table based on increasing atomic weights. Semi-metals are characterized by properties of both metals and non-metals, while alkali metals tend to form ionic rather than covalent compounds.
