Are two types of atoms metallic and nonmetallic?

Answer 1

Metallic and non-metallic is one of many ways of categorizing chemical elements.

Metallic elements have a structure that allows free electrons to migrate from atom to atom within the structure of the material. These are called "conductors".

Nonmetallic elements generally prevent the movement of electrons from atom to atom; they are "insulators".

Starting after World War II, Dr. Robert Shockley developed another class of materials that sometimes would, and sometimes would not, conduct electricity. He called these "semi-conductors", and his discoveries form the basics of modern electronics.

Answer 2

Atoms are classified into metallic and nonmetallic based on their physical and chemical properties. Metal atoms tend to have low ionization energies, are good conductors of electricity, and exhibit a shiny appearance. Nonmetal atoms, on the other hand, have higher ionization energies, are poor conductors of electricity, and often display a dull appearance.
