Question

What information is listed in an element square in the periodic table?

Answer 1

A periodic table given by Mendeleev is a table where all the chemical elements exist on earth. He displayed the patterns in chemical properties of each element. The placement of the elements on the table is important due to the trends of chemical properties in groups and rows.

Complete step by step answer:
One single square on a periodic table indicates the minimum of the name of the element, its atomic weight, and relative atomic mass for a single element. There are some squares which will only show symbols but not the name. However the periodic table includes more information about that element, such as electronic configuration or oxidation states or density etc. The colour indicates the type of elements.

Additional Information:
The elements are classified in terms of groups, periods, and blocks. Groups are also called as families that are vertical columns that are located on the periodic table. This is considered to be a significant form of classification. There are many groups that have elements with similar properties and are referred to with names such as halogens and alkaline earth metals.
Periods are made of horizontal rows of tables. For example, the d-block contains a row of transition metals.
Properties of an element can be predicted based on its location on the table. Trends operate differently when they move vertically and horizontally along the table. This trend within groups is explained by common electronic configuration in their valence shells. This creates likeness in atomic radius, electronegativity, and ionization energy.

Note:
In the periodic table from the top to bottom, the atomic radius of the element increases. Same way the ionization energy and electronegativity decreases due to the electronic configuration. Periods have the same trend in electronegativity, ionization energy, atomic radius as well as electron affinity. When it moves from left to right the atomic radius which causes the ionization energy to increase.
