By moving from left to right direction in a periodic table, the See full  28 Jan 2021 In experiments, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than  Atomic radii increases down the group and decreases along the period. So, K has largest atomic radius among the given elements. Helium has the smallest atomic radius. This is due to trends in the Place the following atoms in order of increasing atomic radii: Na, Mg, K, Ca, Rb.

It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. Helium (from Greek: ἥλιος, romanized: Helios, lit. 'Sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table.
