11 cool facts about the periodic table

The names of the four elements recently discovered have been publicly reviewed. The names of elements 113, 115, 117, and 118 are Nihonium, Moscovium, Tennessine, and Oganesson, respectively. Public review will end in November

The terrible period table of the classroom wall is actually a huge cheat sheet. Clock creator Dmitry Mendeleev has not sent all 63 elements. In order to hurry, he made a database of all elements based on atomic weight.

118 elements are confirmed in the periodic table. Among them, 90 are elements in nature, while others are strict artificial elements. first is the first artificial element

Hydrogen is the lightest element with atomic weight 1. This is the reason to see in the upper left corner of the periodic table.

Helium, neon, argon, krypton, xenon and krypton are called noble gases because they are considered to be unreactive. Recent studies, however, showed active compounds of ruthenium, osmium and osmium.

International Junma Chemical Industry Association (IUPAC) in charge of maintenance cycle

The various forms of pure elements are called allotropes. For example, diamond, graphite, buckminsterfullerene, amorphous carbon are pure element-carbon allotropes.

The Mendeleev elemental periodic table is designed in increasing order of atomic weight whereas the modern periodic table is designed according to increasing atomic number.

In the Periodic Table of Elements, the elements are grouped according to electronic structure. The golden periodic table is in phase 6 (horizontal row) and group 11 (vertical row), and other coin metals such as silver and copper. These metals are very suitable for recycling because of their excellent abrasion resistance. Common functions of the Gold element include low resistance inert and corrosion resistant metals. Use of gold: More than half of the world's gold is used for jewelry, and it usually leads to recycling. One-third is used for investment and stock holding. People can buy gold coins and gold bars for their portfolio. Most gold bars are flat, but some investors in Europe like brick shapes. 12% of gold is used for industries such as mobile phones and can not be reused.

Gold (Au), a chemical element, a dense, glossy yellow precious metal of 11 family (Ib) of the 11th group (Ib) of the periodic table. Gold has various qualities that make it extremely valuable in history. It is attractive in terms of color and brightness, durable and very malleable, and usually present in relatively pure form in its properties. The history of gold is indistinguishable from the history of other metals because it feels the value from the oldest one. Gold is visually comfortable and easy to use, it is one of the first metals to attract attention as it does not discolor and corrode. As an example of a great gold craftsmanship, ancient Egyptians, minos, Assyrians, Etruscans craftmen survived, as an example of many nearly perfect conditions, gold is a very popular material where jewelry and other accessories are made It continues to be. .
