Metallic Character: Metallic character is defined as the property of an element to lose an electron from its valence shell […]

Reactivity of Elements: reactivity of elements is defined in chemistry as the ability of an element to gain or lose electrons.

What is Atomic size / atomic radii Atomic size means the average distance between the nucleus and the valence shell

Electron Affinity: It is the energy released when an electron adds to a gaseous atom’s valence shell to form a

Shielding effect or Screening effect in chemistry: The reduction in force of attraction of the nucleus on the valence shell

Electronegativity is a measure of an atom’s ability to attract an electron pair toward itself in a chemical bond to

What is Ionization energy: Ionization/ionisation energy meaning that the minimum amount of energy in Kj/mol required to remove an electron
