Question

multiple choice 1 point select the atom with the largest atomic radius. sr sc v mn

Explanation:

Atomic radius generally increases down a group and decreases across a period. Sr (strontium) is in Group 2 and Period 5. Sc (scandium), V (vanadium), and Mn (manganese) are in Period 4 and have higher effective - nuclear charges due to more protons in the nucleus for the same principal energy level, resulting in smaller radii compared to Sr.

Answer:

Sr
