===About The Periodic Table===

: The modern [[Periodic Table]] ~~was arranged~~ is based on an earlier [[Periodic Table]] made by a scientist called [[Mendeleev]]. Others had tried to arrange all the [[element]]s before, but [[Mendeleev]] was the first to correctly arrange it by both [[Relative Atomic Mass]] and [[Chemical Property|chemical properties]] with gaps where [[element]]s were later discovered.: The modern [[Periodic Table]] is only slightly different and is arranged by [[Atomic Number]] and [[Chemical Property|chemical properties]].: The columns of the [[Periodic Table]] are called [[Group(Chemistry)|group]]s.: The rows of the [[Periodic Table]] are called [[Period (Chemistry)|~~Period~~period]]s.

===Groups===

: The [[element]]s are arranged [[Group (Chemistry)|group]]s of similar [[Chemical ~~Properties~~Property|chemical properties]].: [[Element]]s have similar [[Chemical ~~Properties~~Property|chemical properties]] when they have the same number of [[electron]]s in the [[Outer Shell]].

====Trends within groups====

The [[Chemical Property|chemical properties]] of [[element]]s within a [[Group (Chemistry)|group]] are similar. However, the [[reactivity]] within a [[Group (Chemistry)|group]] changes as you move up or down the [[Period (Chemistry)|period]]s.*[[Group 1]]: The [[Alkali Metal]]s all react strongly with water. The [[reactivity]] increases as you go down the [[Group (Chemistry)|group]].*[[Group 2]]: The [[Alkali Earth Metal]]s all react strongly with steam and acids. The [[reactivity]] increases as you go down the [[Group (Chemistry)|group]].*[[Group 7]]: The [[Halogen]]s all act as bleaching agents and kill bacteria. The reactivity decreases as you go down the [[Group (Chemistry)|group]].

*[[Group 0]]: The [[Noble Gases]] are all inert (unreactive).

The [[Physical Property|physical properties]] of [[element]]s within a [[Group (Chemistry)|group]] are similar. However, the property changes gradually as you move down the [[Group (Chemistry)|group]].

==Key Stage 4==

===Meaning===

The [[Periodic Table]] is a chart listing all the known [[element]]s arranged in order of [[Atomic Number]] and in columns of [[element]]s with similar [[Property|properties]].

===About The Periodic Table===

: The modern [[Periodic Table]] has the [[element]]s arranged by [[Atomic Number]] and [[Chemical Property|chemical properties]].

: [[Element]]s on the [[Periodic Table]] are written with their [[Chemical Symbol]]s and two numbers representing their [[Relative Atomic Mass]] and [[Atomic Number]].

: The [[Relative Atomic Mass]]es on the [[Periodic Table]] are an [[Mean Average|average]] [[Relative Atomic Mass|atomic mass]] of different [[isotope]]s of the same [[element]].

: The position of an [[element]] in the [[Periodic Table]] is a result of the [[Electronic Structure]] of the [[element]], which itself is due to the [[Atomic Number]] of the [[element]].

: The [[element]]s in each column of the [[Periodic Table]] all have the same number of [[electron]]s in the [[Outer Shell]] (except [[Helium]] in the [[Noble Gas]]es) which causes them all to have the same [[Chemical Property|chemical properties]]. These columns are known as [[Group (Chemistry)|group]]s.

: The [[element]]s in each row of the [[Periodic Table]] all have the same number of [[Electron Shell]]s. These rows are called [[Period (Chemistry)|period]]s.

===History of the Periodic Table===

: Scientists always try to look for patterns to help arrange complicated problems. Many different [[element]]s had been discovered so scientists wanted to arrange them based on patterns they noticed. Some scientists arranged them by patterns in [[Chemical Property|chemical properties]] while others tried to arrange them by patterns in [[Physical Properties|physical properties]] like [[Melting Point|melting point]] or [[Relative Atomic Mass|relative atomic mass]].

: In 1808 a scientist called John Dalton, who created the [[Dalton Model]] of the [[atom]], arranged [[element]]s by their [[Relative Atomic Mass|relative atomic mass]].

: In 1864 a scientist called John Newlands arranged [[element]]s by [[Relative Atomic Mass|relative atomic mass]] but because he noticed that ever 8th [[element]] had similar [[Chemical Property|chemical properties]] he arranged them into what he called 'octaves'. However, he had not taken into account the possibility that some [[element]]s had not been discovered, so he placed some [[element]]s into the wrong groups just to fit the pattern he thought he had seen.

: In 1869 [[Mendeleev]] was the first to place gaps where the [[element]]s did not fit the pattern but still arranged them by both their [[Chemical Property|chemical properties]] and [[Relative Atomic Mass|relative atomic mass]]. This enabled [[Mendeleev]] to [[Prediction|predict]] the existence of [[element]]s that had not yet been discovered.

: [[Mendeleev's Periodic Table|Mendeleev's '''Periodic Table''']] was proven (nearly) correct when new [[element]]s were discovered that fit in the the gaps he had left. This ability of his table to predict the [[property|properties]] of new [[element]]s was what convinced other scientists his '''Periodic Table''' was (nearly) correct.

: There were some problems with [[Mendeleev's Periodic Table|Mendeleev's '''Periodic Table''']] that kept scientists skeptical of it. One such problem was that [[Argon]] has a greater [[Relative Atomic Mass|relative atomic mass]] than [[Potassium]] which would put [[Argon]] in the [[Alkali Metal]]s.

: Once the structure of the [[atom]] was investigated by physicists in the early 1900s it was discovered how to correct [[Mendeleev's Periodic Table|Mendeleev's '''Periodic Table''']] by ordering the [[element]]s by [[Atomic Number|atomic number]] instead of [[Relative Atomic Mass|relative atomic mass]]. This produced the modern '''Periodic Table'''.

==Beyond the Curriculum==

===Isotopes and Atomic Mass===

: While the periodic table provides a snapshot of elements based on their atomic number, it's essential to understand the concept of isotopes. Isotopes are variants of an element with the same number of protons but different numbers of neutrons. This variation in neutron count results in different atomic masses. Therefore, the atomic mass on the periodic table represents an average of these isotopes' masses. Exploring isotopes can deepen your understanding of an element's behavior and its applications in various fields.

===Electron Configuration and Chemical Behavior===

: To truly grasp the periodic table's significance, one must delve into the realm of electron configuration. Each element's position in the table is intricately linked to its electron structure, which, in turn, influences its chemical behavior. Understanding how electrons are arranged within atoms sheds light on why elements in the same group exhibit similar chemical properties while those in the same period differ significantly.

===Applications Beyond Chemistry===

: While the periodic table is a cornerstone of chemistry, its impact extends far beyond the realm of chemical sciences. Elements play vital roles in diverse fields, including materials science, physics, biology, and even everyday life. For instance, the study of semiconductors and their applications in electronics relies heavily on elements like silicon and germanium. By exploring these interdisciplinary connections, you can appreciate how the periodic table underpins advancements in technology, medicine, and various scientific disciplines.

===Recent Discoveries and Superheavy Elements===

: The periodic table is not static; it evolves as scientists continue to explore and discover new elements. In recent years, researchers have pushed the boundaries of the table with the synthesis of superheavy elements, such as nihonium (Nh) and tennessine (Ts). Learning about these groundbreaking discoveries and the challenges involved in creating and studying these elements offers a glimpse into the frontiers of modern science.

===Theoretical Extensions and Uncharted Territory===

: Beyond the known elements, there exist theoretical predictions of even more exotic forms of matter, such as island of stability in superheavy elements. This area of theoretical chemistry and physics explores the possibilities of elements with properties yet to be observed. While these elements may not be part of the periodic table today, they represent the uncharted territory awaiting exploration by future generations of scientists.

By delving into these advanced topics, you can gain a deeper appreciation for the periodic table's role in shaping our understanding of the universe and its ongoing relevance in cutting-edge scientific research.
