Question

explain the difference between metals nonmetals and metalloids

Answer 1

Properties of Metals

Most elements are metals. Metals exhibit the following properties:

usually solid at room temperature (mercury is an exception)

high luster (shiny)

metallic appearance

good conductors of heat and electricity

malleable (can be bent and pounded into thin sheets)

ductile (can be drawn into wire)

corrode or oxidize in air and sea water

usually dense (exceptions include lithium, potassium, and sodium)

may have a very high melting point

readily lose electrons

Properties of Metalloids or Semimetals

Metalloids have some of the properties of metals and some nonmetallic characteristic.

dull or shiny

usually conduct heat and electricity, though not as well as metals

often make good semiconductors

often exist in several forms

often ductile

often malleable

may gain or lose electrons in reactions

Properties of Nonmetals

Nonmetals exhibit very different properties from metals. Nonmetals display some or all of the following characteristics:

dull appearance

usually brittle

poor conductors of heat and electricity

usually less dense, compared to metals

usually low melting point of solids, compared with metals

tend to gain electrons in chemical reactions

Answer 2

A metal is a element which is typically hard, shiny in nature, fusible, malleable and ductile, with good electrical and thermal conductivity.
A non metal is an element that does nothave
the properties of metal.
A metalloid is an element having intermediate
properties of both metal and nonmetal..
