The meaning of PERIODIC LAW is a law in chemistry: the elements when arranged in the order of their atomic numbers show a periodic variation of atomic structure and of most of their properties.
The periodic law is found to help determine many patterns of many different properties of elements; melting and boiling points, densities, electrical conductivity, reactivity, acidic, basic, valance, polarity, and solubility.
The Periodic Law states that the physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number. Many of the properties recur at intervals.
Summary. Elements of the periodic table are arranged in order of increasing atomic number. The periodic law states: "When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties."
What is the “periodic law”? What do the vertical columns (groups) in the periodic table represent?
the law that the properties of the elements are periodic functions of their atomic numbers. Also called Mendeleev's law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.
This principle, known as the Periodic Law, was enunciated by Mendelejeff in two memoirs published in 1869 and 1871, respectively, and the arrangement of the elements, based on this law, which...
The periodic law states that the properties of elements are a periodic function of their atomic numbers. When elements are arranged by increasing atomic number, their chemical and physical properties show a repeating pattern.
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 the same column (group) have similar properties.
Periodic Law states that chemical and physical properties of elements repeat in a predictable way when elements are arranged by increasing atomic number. Why Periodicity Is Important. In essence, periodicity is the guiding principle behind the organization of the modern periodic table.
