Answer 1

The modern periodic table is a tabular display of the chemical elements which are arranged by atomic number, electronic configuration and common chemical properties. We can see some periodic trends in the modern periodic table.

Complete answer:
The seven rows in the periodic table are called periods and the eighteen columns are called groups. The newest elements found in the periodic table are: Nihonium, Moscovium, Tennessine and Oganesson. These four elements were added to the periodic table in June, $2016$ . The symbol of the element Nihonium is $Nh$ and its atomic number is $113$ . The symbol of the element Moscovium is $Mc$ and its atomic number is $115$ . The symbol of the element Tennessine is $Ts$ and its atomic number is $117$ . The symbol of the element Oganesson is $Og$ and its atomic number is $118$ . The US, Russia and Japan were given credit for the discovery of the new elements. Every chemical element has a unique atomic number which represents the number of protons present in its nucleus.
