Atomic radii tend to decrease moving up and right. Thus, inert gases has almost highest radius in a period. (d) The most reactive non-metal: Fluorine (F). In a quantum mechanical description of atomic structure, this period corresponds to the buildup of electrons in the third (n = 3) shell, more specifically filling its 3s and 3p subshells.There is a 3d subshell, but—in compliance with the Aufbau principle—it is not filled until period 4.This makes all eight elements analogs of the period 2 elements in the same exact sequence. Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom. Need assistance? The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. The element which has the largest atomic radius is Cesium.

What contributes to the increase in atomic size within a group in the periodic table as the atomic number increases? Factor Xa Inhibitor Reversal Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom. This is due to the effective nuclear charge increase, or how much more the nucleus pulls in on the electrons. b. Therefore Sodium (Na) has the largest atomic radius. About; Faculty; Journal Club. has the largest electron affinity?d. Elements in the same family have the same number of valence electrons? Each element also adds a proton to the nucleus, so the force pulling the electrons in gets stronger too, so atoms actually get smaller going from left to right across a period. 10:00 AM to 7:00 PM IST all days. At which location in the Periodic Table would the most active metallic element be found? (c) The element with largest atomic radius: Lithium (Li). Academic Partner.
