The atomic size increases from top to bottom and decreases from left to right. Why do atoms get smaller as you move left to right in a period? The # of protons increase, so electrons are more attracted to the nucleus, so the atomic radius is smaller.Click to see full answer. In this regard, what is the periodic trend for atomic size from top to bottom in a group from left to right?Explanation: Electron affinity generally increases from left to right and from bottom to top. Explanation: Periodic trends indicate that atomic radius increases up a group and from left to right across a period. Therefore, oxygen has a smaller atomic radius sulfur.Likewise, what is the trend in atomic size as you proceed down a group? – The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. Beside this, what is the periodic trend for atomic size? Periodic Trend The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.Why does atomic size increase down a group?In general, atomic radius decreases across a period and increases down a group. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
