Match List I with List II
| List I | List II |
| 1. Low Melting point | A. Diamond |
| 2. Lustrous | B. Graphite |
| 3. Hardness | C. Gallium |
| 4. Good conductor | D. Iodine |
Answer & explanation
Correct answer: option 1
The correct answer is option 1. 1-C; 2-D; 3-A; 4-B.
Gallium has a remarkably low melting point compared to the typically high melting points of metals.
Certain non-metals, like iodine, also have a metallic luster in addition to metals.
Non-metals that are allotropes of carbon, such as diamond and graphite, also exhibit outstanding qualities. The hardest material known is diamond, while graphite is a good electrical conductor.
