Non – metals may be either solids, liquids, or gases. Non-metals are poor conductors ofheatand electricity except Graphite. They do not possess metallic luster. Non-metals are not sonorous, they do not produce a ringing sound. Non-metals possess no malleability. ...

Transition Metals less reactive than Group 1 and 2. hard and dense. good conductors of heat and electricity. High mpts, bpts (very strong metallic bond) have coloured ions except for zinc. Non Metals Poor conductors of electricity and heat. Usually have low melting points (11 of them are ...
CHAPTER 6 METALS AND NON METALS
Metal have 1 to 3 electrons in the outer shell whereas non-metal have 4 to 8 electrons. Metal oxide is formed when a metal reacts with oxygen and forms electrovalent or ionic bonds, e whereas non-metals form non-metal oxides when they react with oxygen and mostly form covalent bonds. ...
Non-metals and Semimetals Nonmetals An element that lacks most of the properties of a metal. Poor conductors of heat and electricity Dull and brittle Nonmetals Gases at room temperature: oxygen, nitrogen, fluorine, chlorine, hydrogen, noble gases Solids at room temperature: carbon, iodine, sulfur...
Sorting of all non-ferrous metals using sensor technology ✓ alloy detection ✓ detection of heavy and light elements ✓ high purity in sorted products
How do metals and nonmetals react with water? How are metalloids different from metals and nonmetals? Why do nonmetals form covalent bonds? Explain why can two nonmetals bond together, but two metals cannot? How do metals and nonmetals react with each other?
–Metals tend to have low ionization energies and form (+) ions. –Nonmetals have high electron affinities and tend to form (-) ions. –Compounds of metals and nonmetals tend to be ionic substances. –Compounds of nonmetals are molecular substances. ...
