We are the original creators of the Heritage Periodic Table, an acrylic periodic table with 83 real elements inside. We are also the original creators of the Heritage Personal Museum, a collection of 33 historical artifacts and rare specimens.
Inthe accompanying table, which isa relatively simple type of periodic table, each position gives the name and chemical symbol for the element assigned to that position; its atomic number; itsatomic weight(the weighted average of the masses of its stable isotopes, based on a scale in which carb...
1.2 The periodic table The periodic table provides an invaluable classification of all chemical elements, an element being a collection of atoms of one type. A typical version is shown in Table 1.2. Of the 107 elements which appear, about 90 occur in nature; the remainder are produced in nuc...
The three categories of metals are the alkali metals, the alkaline earth metals and the transition metals. The arrangement of the periodic table comes in handy for keeping these closely grouped; the alkali metals are the six elements directly underneath hydrogen (H) in the far-left column of t...
“island of stability.” Their research, highlighted in prestigious scientific publications, seeks to uncover the properties of elements with over 103 protons and to predict their behavior through theoretical models. This work promises to expand the boundaries of the periodic table and impact a range...

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, ...
