The periodic table classifies chemical elements by their similarities and properties. Each square in the periodic table shows an element's atomic number, its symbol, its name and its atomic weight, which is the number of protons and neutrons the element has.
Many elements on the periodic table have names derived from Latin, including aluminum, calcium, cesium, chlorine, fluorine, gallium, iridium, radium, rubidium and scandium. Other element names are derived from languages such as Greek, Arabic and Anglo-Saxon. Some elements have been named for the cit
The periodic table got its name from the way the elements are arranged in rows, which are called periods. The columns of the table are called groups, some of which have specific names, such as the noble gases and the halogens.
The periodic table's name comes from the fact that it arranges the elements into repeating sets, otherwise known as "periods." These periods are defined by the covalence of an element, the number of electrons it has in its outermost shell and by other elemental attributes. This arrangement places el
In the modern periodic table, elements are arranged by atomic number. They are placed with the lowest atomic number first, and elements with increasing atomic numbers run to the right. They are also arranged in vertical columns known as groups, with these groupings based on shared properties.
The periodic table arranges the known elements in order of increasing atomic number, which typically coincides with increasing atomic mass. Different rows on the table are known as periods. The period number assigned to each element signifies the highest energy level an electron within the element o
Dmitri Mendeleev is widely credited as the creator of the periodic table. A charismatic Russian scientist who was fascinated by chemistry, Mendeleev came up with the idea to organize chemical elements according to their atomic number and other properties. The first periodic table was published by Me
A group on the periodic table is one of the vertical columns found on the table. The elements found in the same group all possess the same number of electrons in their outer orbital shell. These electrons are specifically known as valence electrons.
The elements in the periodic table are organized by their atomic numbers, their electron configurations and the recurring properties found in them. Elements are arranged in blocks, with elements found in that block all containing consistent properties. For instance, all alkali metals are highly reac
Neon is the least reactive element on the periodic table. As a noble gas, neon is colorless and odorless with extremely low reactivity in its natural state. Neon has an atomic number of 10.
