Smallest atomic size in periodic table
Webb24 mars 2024 · The simple answer: Atomic size increases down the group (from top to bottom) and it decreases across the period (from left to right). Now the helium atom is located at the far top-right side of the Periodic table. So according to the Periodic trends, the size of helium atom is the smallest in entire Periodic table.

Did you know?
The atomic radius of a chemical element is a measure of the size of its atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Four widely used definitions of atomic radius are: Van der Waals radius, ionic radius, metallic radius and covalent radius. Typically, because of the difficulty to isolate atoms in order t… WebbImage showing the "anatomy" of a periodic table entry. At the upper left is the atomic number, or number of protons.
