Question

defined element explain the types of element with respect to metal and non metal​

Answer 1

Answer:

Abstract

The definitions of elements and compounds have changed very little in the past 200 years, but chemistry itself has changed a great deal over time. Any form of an element has been considered as the element itself and a compound had to have an exact atomic composition that included two or more different elements. This commentary suggests that only the atomic form of each element should be considered as the element and most other forms should be called elementary substances. A publication of the International Union of Pure and Applied Chemistry (IUPAC) has stated that compounds can be formed by a single element. The author agrees that in terms of modern chemical bonding both heteronuclear and homonuclear molecules can be considered as compounds.

Answer 2

Answer:

Metals

any of a class of elementary substances, as gold, silver, or copper, all of which are crystalline when solid and many of which are characterized by opacity, ductility, conductivity, and a unique luster when freshly fractured. ... such a substance in its pure state, as distinguished from alloys.

Non metal

The non-metals are elements on the right of the periodic table. Non-metals can be gases, liquids or solids. Non-metals are dull in colour, not shiny like metals. ... Non-metals don't conduct electricity well: they are insulators. There is one exception: graphite is a non-metal which can conduct electricity.
