Detailed explanation-1: -Metal: Metal is a category of electropositive elements that usually have a shiny surface, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires.

Detailed explanation-2: -Metals are elements that are good conductors of electric current and heat. They also tend to be shiny and bendable – like copper wire. The majority of elements in the periodic table are metals. They begin on the left side and extend across the periodic table.

Detailed explanation-3: -Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

Detailed explanation-4: -The ability of a material to shine is called lustre. Gold, silver and other metals are examples of lustrous substances.

Detailed explanation-5: -Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).
