For the first time in history, a change will be made to the atomic weights of some elements listed on the Periodic table of the chemical elements posted on walls of chemistry classrooms and on the inside covers of chemistry textbooks worldwide.
Every Element on the Periodic Table contains its details like - Chemical reactions - Balancing chemical equation - Molar Mass - Element Colors - Element Details - Element Density - Element Symbol - Element Number - Element Category - Element Atomic Weight ...
Themodern periodic tableis very similar to Mendeleev's table, but elements today are ordered by increasingatomic number, which reflects the number ofprotonsin an atom. There aren't any "undiscovered" elements, althoughnew elementscan be created that have even higher numbers of protons. ...
is the element that isatomic number2 on the periodic table. Each helium atom has 2protonsin its atomic nucleus. The atomic weight of the element is 4.0026. Helium does not readily form compounds, so it is known in its pure form as a gas. ...
