Physical and chemical properties
In this Class 10 Science topic from the chapter Metals and Non-metals, students learn how to distinguish physical properties from chemical properties and compare metals with non-metals. The topic covers lustre, hardness, malleability, ductility, sonority, conductivity, and melting points, along with chemical reactions involving oxygen, water, acids, and salts. Students also understand reactivity, the formation of ionic compounds, and how these properties explain the uses and behaviour of common elements.
