Lothar Meyer presented his table following Mendeleev, but he disagreed with Mendeleev’s Periodic law. Henry Moseley discovered in 1913 that periodicity is determined by the atomic number rather than the atomic weight. Mendeleev also proposed an elemental periodic system based not only on atomic weights but also on the chemical and physical properties of the elements and their compounds. Mendeleev discovered this principle in 1871, following a number of investigations throughout the nineteenth century.

#Atomic size trend full
Full Stack Development with React & Node JS(Live).Java Programming - Beginner to Advanced.The same trend of atomic radius applies once you divide the table into metal and nonmetal. Ionic radius is the distance from the nucleus to the outer edge of the electron cloud of an ion. Data Structure & Algorithm-Self Paced(C++/JAVA) Metals Nonmetals Ionic radius increases Ionic radius increases.Data Structures & Algorithms in JavaScript.This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. The elements in groups (vertical columns) of the periodic table exhibit similar chemical behavior. Data Structure & Algorithm Classes (Live) Describe and explain the observed trends in atomic size, ionization energy, and electron affinity of the elements.
