पर्याय
Carbon
Nitrogen
Lithium
Beryllium
उत्तर
An element with the largest atomic radius among the following is lithium.
Explanation:
- The second period contains carbon, nitrogen, lithium, and beryllium.
- Over a period, the atomic radius decreases from left to right.
- In the second period, lithium is on the far left.
- Thus, out of C, N, and Be, lithium has the biggest atomic radius.
