There are two main atomic radius trends.The first atomic radius periodic trend is that atomic radii increase as you move downwards in a group.This is due to electron shielding. When an additional shell is added, those new electrons are farther from the atom’s nucleus, which increases atomic ...
Periodic trends in atomic radius Atomic radius tends to decrease on passing along aperiodof the periodic table from left to right, and to increase on descending agroup. This is, in part, because the distribution of electrons is not completely random. The electrons in an atom are arranged in...
An atom will have different radii depending on the bond it forms, so there is no fixed radius of an atom. Atomic Radii are therefore determined by the bonds they form.
Atomic Size & Atomic Radius - Atomic Size is the distance between the center of the nucleus and the outermost shell of electrons is called the atomic radius. Atomic radii can be measured by measuring the distance between the nuclei of atoms in a metal. T

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 ...
