Periodic table chemistry: what to know as a chemistry student

In a language study, the first thing a student starts to learn is the alphabet. In chemistry, a student starts with learning the elements in the periodic table. The periodic table is a table of the elements that are arranged in rows and columns according to their atomic numbers. The first element with an atomic number of 1 is hydrogen. There are seven rows and 18 columns in all.

To get yourself up-to-date on the goings on in chemistry, here are some more information you ought to have on periodic table chemistry.

Dmitri Mendeleev founded the first periodic table

The journey to what we refer to as the periodic table started in 1869 when a Russian chemist called Dmitri Mendeleev founded the periodic table of the elements. In his discovery, he discovered 68 elements and stated that there are yet unknown elements. His assertions were right as more and more elements missing in the table were later discovered by other scientists to fill up the gap in the table.

The total number of elements in the periodic table is now 118

For some time now, the total number of the elements in the periodic table has been between 100 and 114. But recently, four more additions were made to increase the tally to 118. These four new elements were confirmed by IUPAC on December 30, 2015, and later got officially added on Nov 28, 2016. The new addition according to Wikipedia is moscovium, Tennessine,niobium, and Oganesson.

The discovery of elements is a continuous one

One thing that everyone should know is that the elements are substances we come across in everyday life. When Mendeleev founded the first periodic table, he did state that more elements were yet to be discovered. You should know that elements will be discovered as long as life continues to exist.

You may be surprised to know that everything around us is made of these elements. The air we breathe is a mixture of the elements of oxygen and hydrogen, the sand on the earth is the element called silicon. This shows elements are all over us just as periodic table chemistry will remain dynamic.
