However, in the old IUPAC system the letters A and B were designated to the left and right part of the table, while in the CAS system the letters A and B were designated to the main group elements and transition elements respectively. (The preparer of the table arbitrarily could use ...
The periodic table of elementsis familiar to anyone that ever entered a laboratory or classroom. It has no rival in its ability to systematize and rationalize known chemical facts, predict new elements, or suggest fertile areas for further studies. This ingenious and highly functional arrangement of...
Periodic Table of the Elements Periodic Table of the Elements Introduction to the Periodic Table People have known about elements like carbon and gold since ancient time. The elements couldn't be changed using any chemical method. Each element has a unique number of protons. If you examine ...

This is the well-known periodic table of elements, but where each element is labeled by the environment that is created (e.g Supernova explosion etc.).In 2017 the LIGO gravitional wave detector identified the merger of two neutron stars, an event which produces large quantities of gold, ...

1 through 18, are called groups. In the periodic table, elements with similar chemical properties are in the same group. The horizontal rows of the periodic table, from 1 to 7, are called periods. Periods correspond to the number of electron shells possessed by atoms of the elements in tha...
Hydrogen has a single positive charge, like thealkali metals, butat room temperature, it is a gas that doesn't act like a metal. Therefore, hydrogen usually is labeled as a nonmetal. What are theProperties of the Metalloids? Elements that have some properties of metals and some properties ...
