Element having largest atomic radius among the following is :(1) Li (

1.	Element having largest atomic radius among the following is :(1) Li (2) Be (3) B (4) C
Answer» Correct option: (1) Li Explanation: All these four element belong from same period as Li, Be, B, C. On moving left to right across a period atomic size decreases due to increase in effective nuclear charge. Order of increasing atomic radius in given element will be Li > Be> B > C. So Li will have largest atomic radius.

Element having largest atomic radius among the following is :(1) Li (2) Be (3) B (4) C

Answer»

Correct option: (1) Li

Explanation:

All these four element belong from same period as Li, Be, B, C. On moving left to right across a period atomic size decreases due to increase in effective nuclear charge. Order of increasing atomic radius in given element will be Li > Be> B > C.

So Li will have largest atomic radius.
