FAQs
Dmitri Mendeleev developed the first periodic table in 1869. The table arranges elements by increasing atomic number. The elements in the same group (column) are said to have similar chemical properties. 3. The elements were not identified in order of the atomic number 4. The periodic table is even today being updated.
Molybdenum is the 42nd element in the periodic table. This element has a symbol- Mo. Its atomic number is 42.
The father of the periodic table is Dmitri Mendeleev. He was a Russian chemist known for formulating the periodic law and for making the version of the periodic table with elements.
Nitrogen is the number 7 of the periodic table. The number 8 is Oxygen, and the number 9 is Fluorine.
The rarest element is Astatine. This element is radioactive and is considered the longest-lived isotope. It has a lifetime of 8.1 hours. The Earth’s crust has less than 1 gram of astatine.
