What is the simple definition of metal?
A metal (from Greek μέταλλον métallon, “mine, quarry, metal”) is
a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well
. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires).

What is a metal answer?
Metals
are minerals or substances that form naturally below the surface of the Earth
. Most metals are lustrous or shiny. … Metals are natural compounds of earth’s crust, in which they are generally found in the form of metal ores, associated both with each other and with many other elements.
What is metal explain with example?
The definition of metal is
any of the elements with a positive electrical charge, typically with a shiny surface and a good conductor of heat
. An example of metal is gold.
What is metal and its types?
Metals can be divided into two main groups: ferrous metals are those which contain iron and
non-ferrous metals
that are those which contain no iron. Ferrous Metals. Pure Iron is of little use as an engineering material because it is too soft and ductile.
What is metal in your own words?
(Entry 1 of 2) 1 :
any of various opaque, fusible, ductile, and typically lustrous substances that
are good conductors of electricity and heat, form cations by loss of electrons, and yield basic oxides and hydroxides especially : one that is a chemical element as distinguished from an alloy.
What is non metal in simple words?
The definition of nonmetal is
an element that doesn’t have the characteristics of metal
including: ability to conduct heat or electricity, luster, or flexibility. An example of a nonmetal element is carbon.
