Hint:Metals and Nonmetals are various types of materials present around us. Elements can be classified into metals and nonmetals and it is vital to know if a particular element is a metal or nonmetal. Metals such as copper and aluminium are good conductors of heat and electricity, whereas nonmetals like phosphorus and sulfur are insulators.
Complete step by step answer:
We can say the majority elements in the periodic table are metals. This comprises alkali metals, transition metals, lanthanides, actinides and alkaline earth metals.
We have listed some physical properties of metals as,
Shiny (lustrous) in nature
High Density and melting point
Malleable
Ductile
At room temperature, metals are in solid form other than mercury
Opaque
We can say very few elements in the periodic table are non-metals. These are found on the right-hand side in the periodic table. Elements which are under non-metals are sulphur, carbon, all halogens, phosphorus, hydrogen, oxygen, selenium, nitrogen and noble gases.
We have listed some physical properties of non-metals as,
Poor conductors of electricity and heat
Non-ductile materials
Brittle solids
Maybe solids, liquids or gases at room temperature
These are not sonorous
Transparent
We know that coal is nothing but a solid form of carbon, and it appears as black in colour.
Coal is a non-metal. Coal is neither malleable nor ductile. It is brittle. It would break if we try to draw it into a wire.
Therefore, the answer is false and so it is zero.
Note:
We must remember that nonmetals and metals occur in different forms (allotropes). They have diverse shapes and properties. Metals are good reducing agents and non-metals are good oxidizing agents. Metals have low electronegativities, whereas non-metals are highly electronegative.
Some of the uses of non-metals are,
Oxygen is a non-metal which is used for breathing by plants and animals. It is needed to maintain our life. It is used in the fuel-burning process in homes, factories, and vehicles for transport.
The non-metal used in the rockets is liquid hydrogen. There are separate hydrogen and oxygen tanks which combine and burn to begin the rocket. Because of its high calorific value, hydrogen is used.
