Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t
In this article, we'll break down everything you need to know about the periodic table. From its history and layout to its key elements and groups
Periodic table - Elements, Groups, Properties: The noble gases—helium, neon, argon, krypton, xenon, radon, and oganesson—have the striking chemical property of forming few chemical compounds. This property would depend upon their possessing especially

The Modern Periodic Table Our current periodic table shows elements in order of increasing atomic number (#protons) Elements in the same column have similar properties, and are called a group or family. Groups are designated in two ways: A Roman numeral (I through VIII) and a letter (A or...
The names were chosen to honor the laboratories that first created the elements: the Flerov Laboratory of Nuclear Reactions in Dubna, Russia, and Lawrence Livermore National Laboratory in Livermore, Calif. Scientists at the two institutions collaborated to synthesize both of these heavy elements by ...
Periods are the rows of the periodic table, groups are the columns. Every element has a unique combination of period and group, and a unique atomic number.Explanations (5) Lydia Kim Text 4 Reading the Periodic Table The periodic table is a chart with all the known elements. We've all ...
