The article gives examples of trends in properties of the elements, their ions, and their compounds, which can usefully be examined from the perspective of the periodic table as a whole, rather than by looking at one group of elements (or even individual elements) at a time. The properties...
Mendeleev's periodic table of elements. The periodic table classifies all chemical elements according to their atomic number and chemical properties.
One reason the periodic table of the elements is so useful is that it is a means of arranging elements according to their similar properties. This is what is meant by periodicity orperiodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into meta...

Periodic table - Elements, Properties, Periodicity: The periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stabl
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
The periodic table's organization provides important information about an element's structure and properties. Read on to learn more about how the periodic table was made over 150 years ago and why it's used today. Related:Periodic table of elements quiz: How many elements can you name in 10...
