Best ResponseYou've already chosen the best response.1#2: What happens to the atomic size of the elements as one goes from the bottom to the top of a group? A. Atomic size stays the same as one moves from bottom to top in a group. B. Atomic size decreases as one moves from bottom to top in a group. C. Atomic size increases as one moves from bottom to top in a group. D. Atomic size changes randomly as one moves from bottom to top in a group. **my answer: C. is that right??

Best ResponseYou've already chosen the best response.1bottom = heavier elements top = lighter elements (think of it as like the heavy stuff floats to the bottom of the pool while the light/lighter stuff floats to the top) so as you go from bottom > top, the size decreases

Best ResponseYou've already chosen the best response.1it's not C because it's not increasing
