Why National Periodic Table Day?
Today is the National periodic Table Day.Hope,periodic table does not need any introduction.nonetheless,let me define for the forgetters.It is a tabular composition of chemical elements in accordance with their chemical properties and atomic number.Honestly,i learnt chemistry as a subject for around 6 years but still I don’t know the exact arrangement and even some name of the chemical elements too.The day is recognized to explore more about the periodic table and the chemist who discovered the chemical elements and its chemical reactions.
How we can Celebrate National Periodic Table Day:
Use #PeriodicTableDay to post regarding periodic table on social media.Let’s have a challenge,post about the periodic table elements precisely ordered by their chemical properties using some memory technics so that it would be helpful for the students/explorers to remember.
You just try some technics on atomic number basis.
Interesting Facts About National Periodic Table Day:
The first acknowledged Periodic table was invented by Dmitri Ivanovich Mendeleev,a Russian chemist during the year 1869.prior to that,a table with 56 elements was published by John Newlands,an English Chemist during the year 1863 and to recognize this table,this day is credited.
The elements with same chemical behavior is arranged in center where as the metals and non metals are arranged to the left and right respectively.
Before the invention of periodic tables,only few elements are identified and used by ancient people.
Elements like Gold, silver,carbon, copper,tin, iron, lead, mercury and sulfur are the first ancient used elements.
As of 2015, Out of the 118,94 elements were discovered naturally from the earth.Rest of the 24 elements discovered by laboratory experiments.
All the 118 elements as of 2015 are officially proclaimed by International Union of Pure and Applied Chemistry (IUPAC).
Hydrogen, Chromium,Beryllium, Plutonium, Fluorine,Lead,Polonium,Arsenic, Caesium, Mercury are some of the dangerous and toxic elements.
All living organisms constitute chemical elements that mainly includes Oxygen,Hydrogen,Carbon,Nitrogen,calcium and phosphorus.very little proportion of sodium,potassium,magnesium,sulfur and chlorine are also present depending upon the species.
Gold,Silver,copper,Bronze,platinum,Rhodium are the widely used elements in jewellery making.
Few Questions/Answer about elements:
1.which is the costliest element in periodic table?
Francium,also note,it will disappear within few minutes right after the creation.
2.which is the most dangerous element?
Plutonium, nevertheless,few other chemical elements like mercury,Beryllium are also highly dangerous.
3.which is the most used element in jewellery making?
Gold and platinum.
4.which chemical element causes immediate death?
Arsenic,Polonium and Mercury are equally and highly dangerous.
5.what are the chemical elements used for medical purpose?
Gold,platinum,Zinc,Lithium,Silver,combination of Platinum, Titanium, Vanadium, Iron is used to treat cancer cells.
Hope the above are useful to you guys,Happy periodic table day.
History of National Periodic Table Day:
Mr. David T. Steineker, basically a chemistry teacher of Jefferson County Public Schools recommended a day to applaud and encourage the chemists who involved in preparing the modern period table.Moreover,he put forward February 7 since on the same day in 1863,the first periodic table was established.
