Who uses the Periodic Table?

The periodic table is used beyond the classroom mostly in the scientific community. It provides a wealth of information to scientists when they are considering new discoveries and compounds. It is used by engineers and designers when choosing materials and elements for technology. It also has big implications for economies when considering the prices of different metals and precious commodities traded internationally.

For example the use of Ytrium in the production of mobile phone screens can impact directly on the price of the phone, if engineers know the price of Ytrium is high they may look for an alternative metal to use and by using the periodic table they can find elements with similar properties that may be more abundant and cheaper. In the case of pharmaceutical companies they may use the periodic table to identify elements for use in their drugs and treatments. By studying nature and the way metals and non metals are incorporated into biological organisms scientists are able to use the periodic table to find elements to replace these molecules and create new drugs.

Terms in section
Corpuscularism

Corpuscularism was a theory proposed by Descartes that all matter was composed of tiny particles.

Rene Descartes

Rene Descartes was a famous mathematician and philosopher of the 16th century who hypothesised the theory of corpuscularism about the atom

Luster

Luster is a term for a reflective surface that reflects light giving a shiny appearance.

Semi conductors

Semi conductors is a term to describe metalloids that are able to conduct a current when electrical energy is applied due to the movement of electrons but the conductivity measurements are not as high as metals due to fewer electrons to carry a charge or a less ordered structure.

Ionic compound

An ionic compound is a bond that forms between metals and non metals to form a large ionic lattice

Nuclear Fusion

Nuclear fusion is a process which occurs in. the sun. Hydrogen atoms under a lot of heat and pressure are forced together to make a larger atom of helium

Uncertainty Principle

Heisenberg’s uncertainty principle is used to describe the relationship between the momentum and position of an electron. Where by if the exact position of the electron is known the momentum will be uncertain.

Heisenberg

Werner Heisenberg was a German physicist who was a pioneer in the field of quantum mechanics. He devised the principle of uncertainty relating to the momentum and position of an electron.

Lobes

Quantum Numbers

Quantum numbers is a term used to describe the assigning of numbers to electrons as a mathematical function to describe their momentum and energy.
