Periodic Table of Elements
The Periodic table of elements, simply called a Periodic Table, is a systematic arrangement of 118 known chemical elements. These chemical elements are organized in order of increasing atomic number, or the number of protons in an atom's nucleus, which typically corresponds with increasing atomic mass, from left to right and …

The Beginner's Guide To The Periodic Table Of Elements
The periodic table as we use it today was created by Dmitri Mendeleev in 1869. However, Mendeleev's table was not the first attempt at bringing order to the elements. As early as 1789, chemists like Antione Lavoisier attempted to group the known elements scientifically. Lavoisier grouped them as gases, metals, nonmetals, and earths.

Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).

There are seven (or eight) total periods. The first one is short and only has two elements, hydrogen and helium. The sixth period has 32 elements. In each period the left most element has 1 electron in its outer shell and the right most element has a full shell. Groups. Groups are the columns of the periodic table.

Modern Periodic Table of Elements -Law,Features, Classification …
The modern periodic table of elements can be broken down into 4 blocks – the s-block, the p-block, the d-block, and the f-block. This classification is based on the types of orbitals that contain the valence electrons of the element. For example, s-block elements have valence electrons in s-orbitals and d-block elements have their valence ...

Periodic Table Definition in Chemistry
The periodic table is a tabular arrangement of chemical elements that is arranged by increasing atomic number and groups elements according to recurring properties. The seven rows of the periodic table are called periods. The rows are arranged so that metals are on the left side of the table and nonmetals are on the right side.

Element List
There are 118 elements on the periodic table. Each element is identified by the number of protons in its atoms. This number is the atomic number. The periodic table lists the elements in order of increasing atomic number. Each element has a symbol, which is one or two letters. The first letter is always capitalized.
