The Periodic Table of the elements is a tool that is used to classify the most representative inorganic chemical elements, divided into groups (vertical lines) and periods (horizontal lines). The elements are divided into metals, non metals and metalloids (metals).
I metals elements are widespread, malleable, ductile and can be processed to be cut into smaller sheets. Have a high electrical conductivity, high thermal conductivity and are shiny. Among the metals include sodium (Na), beryllium (Be), Magnesium (Mg), aluminum (Al), potassium (K), iron (Fe), cobalt (Co), copper ( Cu), nickel (Ni) and so on.
I non-metals have properties opposite to metals (low electrical and thermal conductivity, low ductility and malleability). These are elements such as hydrogen (H), sulfur (S), phosphorus (P), nitrogen (N), chlorine (Cl), oxygen (O), etc..
I metalloids still have different properties, which are between metals and non-metals. This is the boron (B), Silicon (Si), arsenic (As), tellurium (Te), germanium (Ge).

Each element of the table periodical has its own atomic number (top left corner), an atomic weight (in the upper right corner), the symbol (in the case Iron Fe for example), the name immediately below the symbol, and the electronic configuration, data from orbit.
The atomic number indicates the number of protons in the atomic nucleus and is indicated with the letter Z. The atomic weight is the mass of an atom of the element, expressed in atomic mass units. The electronic configuration is the arrangement of electrons around the nucleus of an atom (or more nuclei of atoms).
Here you find the table interactive periodic ! We will return very useful in your studies!
