8.6: Periodic Trends in the Size of Atoms and Effective Nuclear …

WebbThe greater attraction draws the electrons closer to the protons, decreasing the size of the particle. Therefore, the atomic radius decreases. Down the groups, atomic radius increases. This is because there are … WebbThis causes the electrons to be pulled closer to the nucleus, making the atomic radius smaller. On the other hand, as we move down a group in the periodic table (Na to Rb), the number of energy levels or shells increases, resulting in an increase in the distance between the nucleus and the outermost electrons. This results in a larger atomic ... cookie clicker game 4 https://sienapassioneefollia.com
