Question
- The elements with the smallest atomic radii tend to be found in which part of the periodic table?1 pointThe upper left cornerThe bottom left cornerThe bottom right cornerThe upper right cornerThe inner transition metals
Solution
The elements with the smallest atomic radii tend to be found in the upper right corner of the periodic table.
Here's why:
-
Atomic radius decreases as you move from left to right across a period in the periodic table. This is because as you move across a period, each atom has more protons in its nucleus and more electrons in its energy levels. The increased number of protons creates a stronger positive charge, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
-
Atomic radius also decreases as you move from the bottom to the top of a group in the periodic table. This is because as you move up a group, there are fewer energy levels, so the outermost electrons are closer to the nucleus, resulting in a smaller atomic radius.
Therefore, the elements with the smallest atomic radii are found in the upper right corner of the periodic table.
