A period on the periodic table is a horizontal grouping of elements running from the left to right of the table. Several trends are observed going from the left side of the periodic table to the right.
Co in the periodic table of elements is cobalt. Located in group nine, period four of the periodic table, this transition metal has an atomic number of 27 and an atomic weight of 58.9. It is a hard element that appears bluish-gray in color.
The Periodic Table offers basic information about each one of the known chemical elements. Each element has its own box in the table, and these boxes include the element's atomic number, atomic weight and chemical symbol. An element's position on the table indicates which elements share its basic pr
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.
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
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.
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.
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
Because the period table contains so much information, people have varying definitions of what it means to learn it; however, the Edcoogle website's blog contains mnemonics to help people memorize the elements' positions, and Quizlet has ready-made flashcards for learning the elements' names.

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
