Periodic Table Calculator gives output Chemical element details like atomic weight, atomic number, atomic properties, nuclear properties, electromagnetic properties, invented by, number of isotopes etc. Just place your mouse pointer on the element name then automatically it will display the entire information of the particular element .

Periodic Table - Definition

Periodic table is a tabular display of the chemical elements which were arranged by their atomic number, electronic configuration and recurring chemical properties. The structure of the table shows periodic table trends. The seven rows of the table called periods generally have metals on the left side and nonmetals on the right side.

The eighteen columns are called group containing elements with similar chemical behaviour. 118 elements are naturally occurring elements and the rest are made.Elements arranged in left to right, top to bottom in increasing order of atomic number. The elements in the same group have the same valency and chemical properties.

Uses of Periodic Table

  • By using a periodic table we can distinguish between metals, non metals, and metalloids.
  • By using this we can measure electronic configuration of elements.
  • Using this we can determine melting and boiling points of elements.
  • By using a periodic table we can determine the atomic radius and ionic radius of an element.
  • We can know about blocks of elements and also can measure atomic number, electronic configuration and ionization energy of elements.

Lanthanides are the rare-earth elements, they are a group of elements from lanthanum (Atomic number 57) to Lutetium ( Atomic number 71). So there are 15 elements in the lanthanide series. Each element in the lanthanide series has a valency of +3. Lanthanides belong to the 6th period and 3rd group(1st group of d-block).
