Understanding Atomic Radius Trends: The 2 Key Principles

Web31 de ago. de 2024 · If this explanation is true, then the rate of declination in atomic radius should decrease as you consider each period in turn. And that is exactly what is observed. And if this explanation is true, then you should observe almost no change in atomic radius as you march across the Periodic Table, by the time you get to uranium. WebAnother way to explain the trend in atomic radius across a period is in terms of the effective nuclear charge experienced by the valence electrons. Since the valence electrons are furthest from the nucleus (outer most level) the inner core electrons (shown in red in the table above) shield the outer electrons from some of the positive charge on the nucleus. Web14 de set. de 2024 · 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. 10.
