Respuesta :
Of the following atoms (oxygen, sulfur, selenium, tellurium, and polonium), oxygen has the smallest atomic radius. In the periodic table, the trend atomic radius is increases down the group.
Atomic radius is one of the periodic properties defined in the periodic table. Atomic radius is the distance to the nucleus that accounts for 95% of the electron load of the density. It can be defined as a function of internuclear distance. This distance varies, depending on whether the atoms are connected by chemical bonds or simply touching without forming a bond.
Atomic radius is a periodic property that increases with period (top to bottom) and decreases with group (left to right). Additional electron shells are added because the atomic radius increases with the number of planes occupied.
The elements when arranged from smallest to largest atomic radius is given as;
Oxygen < Sulfur < Selenium < Tellurium < Polonium
therefore the smallest atomic radius is oxygen.
