Question

I want to know about metal and non metal

Answer 1

Answer:

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.

Explanation:

Metals contain 1 to 3 electrons in their outermost shell whereas non-metals contain 4 to 8 electrons in their outermost shell. Metal loses electrons to form electropositive ions but non-metals accept electrons to form electronegative ions.

Answer 2

In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. ... A modern definition of metals is that they have overlapping conduction bands and valence bands in their electronic structure.Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel.

In chemistry, a nonmetal is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity.Hydrogen, hydrogen, chlorine, fluorine, carbon, nitrogen, arsenic, phosphorus, selenium are examples of non-metal.
