Metals and non metal Metals react with oxygen to produce oxides which are alkarine in nature. Can you look around and see if they exist in your surroundings? ; Conduction: They are poor conductors of heat and electricity. CHEMICAL PROPERTIES OF METALS What happens when metals are burnt in air?- Almost all metals combine with oxygen to form metal oxide. The metals have a lustrous surface; they can also be polished for obtaining a highly reflective surface. More than 110 elements are known today. Non-metals are non-lustrous and cannot be polished. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Your email address will not be published. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. These elements were classified by Lavoisier in to metals and non-metals by studying their properties. 6. The reactivity of metalloids depends on the properties of the elements they are interacting with. Non-metals are used in small quantities but are very vital in daily life. 5. Poor conductors of electricity and heat; Non-Ductile metals; Brittle solids Intro to physical properties of metals.
