From the atomic numbers given, the corresponding elements has to be identified and has to be labeled as noble gas, halogen, alkali metal, alkaline earth metal, transition metal , lanthanide or actinide. Concept introduction: Atom is the smallest fundamental unit of matter. Atom is made up of subatomic particles like electrons, protons and neutrons. Protons and neutrons are present in the nucleus and called nucleons. Electrons are present in orbitals, outside the nucleus. During chemical transformations electrons are being exchanged between the elements. Atomic number is the number of electrons or the number of protons present in that atom. It is the main characteristic of an atom on which most of the properties are dependent.

Electrons are present in orbitals, outside the nucleus. During chemical transformations electrons are being exchanged between the elements.

Atomic number is the number of electrons or the number of protons present in that atom. It is the main characteristic of an atom on which most of the properties are dependent.
