The Metallic character refers to elements that exhibit ductility, malleability, and luster due to their atomic structure. Metals are typically shiny, malleable, and good conductors of heat and electricity.
Examples of metals include:
Iron
Copper
Aluminum
Silver
Non-metallic elements, on the other hand, lack these characteristics and are typically ductile but not malleable or shiny. They are poor conductors of heat and electricity.
Examples of non-metals include:
Carbon
Hydrogen
Nitrogen
Oxygen
The difference between metals and non-metals can be attributed to the number of valence electrons present in their atomic orbitals. Valence electrons are the electrons located in the outermost energy level, which are responsible for chemical bonding. Elements in the same group of the periodic table have the same number of valence electrons, resulting in similar properties
