The Periodic Table

Peroiodic Table

The elements on the periodic table are organized by their atomic number. The elements are represented by symbols called the chemical symbol. For example, Hydrogen is represented by the chemical symbol H. The way the organization came to be is when Dmitri Mendeleev was putting cards that had the element names on them in chronological order. It’s organized by metals, non metals and semi-metals/metalloids. There’s Alkali metals, Alkaline metals, and inert/Nobel gasses.


Some examples of metals are Gold (Au), Mercury (Hg), Copper (Cu), and Aluminum (Al). Pretty much all of the metals are in solid form at room temperature except Mercury (Hg). The different types of metals found on the periodic table are the Alkali metals, Alkaline earth metals, and other metals. The metals found on the periodic table are shiny. All metals are ductile and malleable, which means they can be stretched and/or bent. Metals can conduct electricity fairly well, and they also can conduct heat. Melting points of metals can get to pretty high temperatures. For example, the melting point of aluminum (Al) is 1220 degrees Fahrenheit. They also react with acid.


Semi-metals or Metalloids are found next to the border that separates the metals from the non metals. Some examples of semi-metals are Silicon (Si), Arsenic (As), and Antimony (Sb). Most metalloids are brittle a d dull.


Dmitri Mendeleev was born in Tobolsk, Siberia in 1834 and died in. He organized the periodic table by atomic numbers and in groups of how reactive they were.

All the elements to the right of the zig zag line on the periodic table are gases. Nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids and some are gases.

Non Metals

The periodic table is a table of the chemical elements arranged in order of atomic number, usually in rows, or groups.

The alkali metals, found in group 1 of the periodic table are the most reactive elements on the periodic table. Theyre organized from the lowest reactive one, which is at the top, to the highest reactive one, which is at the bottom. They are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals.
