Nomenclature of elements: Introduction
The Periodic Table of Elements is a tabular display of the chemical elements, ordered by increasing atomic number. The elements are arranged in rows (periods) and columns (groups), with the elements in each group having similar chemical and physical properties. In addition, the table is divided into blocks, which are groupings of related elements.
The table is named for its creator, Dmitri Mendeleev. Mendeleev published the first version of the table in 1869, and over the years, the table has been updated as new elements have been discovered.
How The Elements With The Atomic Number (Z) Above 100 Assigned Names?
The elements with the atomic number (Z) above 100 are assigned names according to the alphabetical order of their atomic number. For example, element with the atomic number (Z) of 103 is called “Iodine.”
Nomenclature Of Elements With Atomic Number (Z) Greater Than 100
The table of the elements is a periodic table that arranges the chemical elements in order of atomic number. The table is divided into seven periods and 18 groups. The periods are each divided into blocks that are named for their characteristic electron configurations.
The first period consists of only one element, hydrogen. The second period consists of two elements, helium and lithium. The third period consists of eight elements, including beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, and sodium. The fourth period consists of 18 elements, including argon, potassium, calcium, and titanium. The fifth period consists of 32 elements, including copper, germanium, and zinc. The sixth period consists of 54 elements, including tungsten, xenon, and zirconium. The seventh period is still under development and has not been completed.
The 18 groups are each divided into subgroups that are named for their characteristic elements. The main group of the table is the first group, which consists of the alkali metals. The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium. The second group is the alkaline earth metals, which consists of beryllium, magnesium, calcium, strontium, barium, and radium. The third group is the halogens, which consists of fluorine, chlorine, bromine, iodine, and astatine.
