Why does atomic radius decrease across a period on the periodic table of elements? Atomic radius decreases across a period on the periodic table because, when moving from left to right across a row, there are more electrons in the valence shell and more protons in the nucleus. These additiona...

We select the element that has the largest atomic radius. We can refer to the periodic table of elements wherein the increasing period and the... Learn more about this topic: The Periodic Table Lesson for Kids: Structure & Uses from ...
Many references give table of atomic radii. Sometimes in text books and other sources, the rather vague term "atomic radius" is not defined and in such cases it is therefore not clear what the values actually mean. The values given here for atomic radius are calculated values using methods ...
The atomic radius trend describes how the atomic radius changes as you move across the periodic table of the elements. In general, the atomic radius of an element tends to increase as you move down an element group in the periodic table. To understand wh

The two atomic radius trends we discussed above are true for the majority of the periodic table of elements.However, there are a few exceptions to these trends. One exception is the noble gases. The six noble gases, in group 18 of the periodic table, are helium (He), neon (Ne), argon...
