what is metals and non metals
Answers
Answer⏩
METALS:
All elements except hydrogen, which form positive ions by losing electrons during chemical reactions are called metals.
Metals are lustrous, malleable, ductile, good conductors of heat and electricity.
NON METALS:
Elements that tend to gain electrons to form anions during chemical reactions are called non-metals.
These are electronegative elements.
They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gaseous, liquids or solids.
Explanation:
Difference Between Metals And Nonmetals. Metals and Nonmetals are different types of materials present around us. ... Metals (like copper and aluminium) are good conductors of heat and electricity, while nonmetals (such as phosphorus and sulfur) are insulators.
METALS
Metals are materials holding or possessing the characteristics of being shiny, hard, fusible, malleable, ductile, etc. Few examples of metals (materials) are – Gold, Silver, Aluminium, Copper, Iron, etc.
NON METALS
Non – metals are materials not holding the characteristics of metals, means they are not shiny, hard, fusible, malleable, ductile, etc. Many materials like coal and Sulphur are very soft and dull in appearance. They break down into very fine thin powdery mass on tapping with the hammer. They are neither in – sonorous and also are a very poor conductor of heat and electricity. Few examples of non – metals are carbon, oxygen, Sulphur, etc.
