Introduction
• D block elements belong to Groups 3 to 12 • Their inner d orbitals are filled by electrons and are therefore referred to as d-Block Elements. • These elements have the general outer electronic configuration (n-1)d1-10ns0-2 • They are all metals. • They mostly form coloured ions, exhibit variable valence (oxidation states), Para magnetism and oftenly used as catalysts.
Pre-Requisites:
Element, periodic properties, classification, electronic configuration, shells, orbital
Activity:
Objects with similar usage or characteristics fall in the same group.
Real Life Question:
Where does the blue paint get its blue color from?
