What is as periodic table?

The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.

What is FE on the periodic table?

Fe. Iron. 55.847. Fe comes from the Latin name, ferrum. 36.

How is the periodic table arranged?

In the modern periodic table, the elements are listed in order of increasing atomic number. In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group).

How is the periodic table used?

Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius.

What is CL on the periodic table?

chlorine (Cl), chemical element, the second lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Chlorine is a toxic, corrosive, greenish yellow gas that is irritating to the eyes and to the respiratory system.

Why is iron called Fe?

The name derives from the Anglo-Saxon iron of unknown origin. The element has been known from prehistoric times. The symbol Fe is derived from the Latin ferrum for “firmness”.

Who arranged the periodic table?

chemist Dmitri Mendeleev
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered. While arranging the elements according to their atomic weight, if he found that they did not fit into the group he would rearrange them.
