what are the characteristics of metals and nonmetals?

['They are solid (with the exception of mercury, Hg, a liquid).', 'They are shiny, good conductors of electricity and heat.', 'They are ductile (they can be drawn into thin wires).', 'They are malleable (they can be easily hammered into very thin sheets).']

Most elements are metals. They are usually shiny, very dense, and only melt at high temperatures. Their shape can be easily changed into thin wires or sheets without breaking. ... Elements that have properties of both metals and nonmetals are called metalloids.
752818
Most elements are metals. Nonmetals are located on the righthand side of the periodic table. Metalloids have properties of both metals and nonmetals.

['Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). ... ', 'Non-Malleable and Ductile: Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets.', 'Conduction: They are poor conductors of heat and electricity.']

Metals are solids, non metals are gasses and metalloids are in between metals and non metals. Also, metals have there atoms all close and packed, non metals have there atoms far apart, and metalloids have there atoms either close or far apart. Metals are separated form the non metals in the periodic table.

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.

Three characteristics of metals are their good conductivity, malleability, and shiny appearance. Metals are good conductors of heat and electricity,...

In chemistry, a nonmetal (or non-metal) 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.

There are many differences like physical and chemical . like metals are generally hard , sonorus, ductile ,lustorus ,malleable etc and non metals are soft non malleable and non ductile. Metals have generally high melting point and boiling point. and they are good conductors of heat and electricity.
858457
Elements like O (oxygen) and H (hydrogen) are members of nonmetals. They can be a solid or a gas at room temperature. They have an appearance that is dull or without luster.
729250
Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental nonmetals are gases at room temperature, while others are liquids and others are solids. The metalloids are intermediate in their properties.

Comparison Of Chemical Properties Of Metals And Non-metals Metals on reacting with water form metal oxides or metal hydroxides and release H2 gas. Non-metals cannot give electrons to hydrogen in water to be released as H2 gas. Non-metals have no reaction with water. Metals react with oxygen to form basic oxides.
