Atomic size measured the distance between the nucleus of an atom and the outermost non-valence electrons of the atom. Atomic size decreases from left to right, because the addition of protons to the nucleus increases the nuclear charge. Atomic size tends to increase from top to bottom because of the additional rings of electrons.

At first thought, you might think well this might be a fairly straight-forward thing. ... let's think about what the trends for atomic size or atomic radii would be in the ...

en.wikipedia.org/wiki/Atomic_radius

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.

In general, the trend of the ionic radius has a similar trend to the atomic radius, increasing in size as you move across the periodic table. Other Trends Found In The Periodic Table. There are other trends to be found in the periodic table, apart from the atomic radius trend.

Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radius, ionic radius, metallic character, and chemical reactivity.

Atomic radius is a more definite and measurable way of defining atomic size. It is the distance from the center of one atom to the center of another atom in a homonuclear diatomic molecule. There are three factors that help in the prediction of the trends in the Periodic Table: number of protons in the nucleus, number of shells, and shielding ...
