Period (periodic table) - Wikipedia
WebThe periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the problem of organizing the elements, but Dmitri Mendeleev published his first version of the periodic table in 1869, and is most often credited as its inventor. WebBy convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior.Devised by Russian chemist Dmitri Mendeleev (1834–1907) in 1869, the table places elements into columns—groups—and rows—periods—that share certain properties.These properties determine an element’s … Web16 31 16 16 15 S. f NUCLEAR REACTION. • Change in the identity or characteristics of. an atomic nucleus, induced by bombarding. it with an energetic particle.
