Hello guys, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Metals and Non-Metals. Metallic and non-metallic are different with each other due to change in some physical and chemical features. non-metallic substances are soft in nature due to weak atomic bonds. Metallic substances are hard in nature due to the existence of a strong metallic bond among the atoms. Metal is a material through which current can passes. They are coming to make different sheets after the application of force. metals are chemical material like iron alloy
In today’s post, we will discuss the different features and parameters of both metals and non-metals substances and compare them to find their differences. So let’s get started with the Difference Between Metals and Non-Metals.
Difference Between Metals and Non-Metals
Metals
- Such substances that has one to three electrons in the outermost shell are called metals except for hydrogen.
- Metals except mercury and gallium exist in solid form.
- Their density is high.
- Metals formed cations.
- Metallic elements are good conductors and current can pass through them easily.
- Their tensile strength is high.
- Their melting and boiling point is large.
- The present in the periodic table on the left side.
- A metallic bond exists between metals.
- Metals are malleable and ductile in nature.
- Their structure is hard.
- After the reaction with the oxygen metals form basic oxides.
- After the reaction with the acids creates hydrogen.
Examples of Metals
- The commonly found metals are iron, gold, Copper Aluminum, lead-silver, etc.
Wha is Alloy
- Alloy is a substance that shows the properties of metal and created through the use of 2 or more 2 metallic substances. Their physical structure can have fixed or changeable structures
- the alloy created through the use of gold and silver has a changeable quantity of gold according to the structure.
- The pure shape of the metallic substance is soft brittle and takes part in different reactions.
- The features and parameters of alloy can be changes through the use of different quantity sof metallics according to requirements
- The main benefit of these substances is that they are less resistant and less effective through corrosion so it mostly employed.
Non-Metals
- Such substances that have four to seven electrons in the valence shell are called non-metals.
- The conductive behavior is less or current can not flow through them.
- Their tensile strength is less.
- Their melting point is less than the metals.
- Metals are present at the right side of the periodic table.
- After reaction with the oxygen, they create acidic oxides.
- Their nature is electronegative.
- A covalent bond is present between the nonmetals atoms.
- Their physical state can be solid, gas and liquid.
- Their density is less.
- Non-metals create anions.
- Their nature as compared to metals is non-malleable and non-ductile.
- Their structure is soft compare to the metals.
- Non metals do not show a reaction with the acids.
Examples Non Metals
- Examples of non-metals are oxygen, carbon, sulphur, iodine, etc.
Properties of Metals
Heat resistance:
- Metals come with high melting and boiling points and have solid designs for high temperatures.
Conductivity:
- Metal has features to conduct current and heat since it has free electrons that move easily in metal and cause current in the form of thermal and electrical.
Malleability and ductility:
- Metals have malleable and ductile features, and they can be transformed into different shapes and wires without breaking.
Luster:
- Different metals come with a shiny look that is called luster that reflects light.
Density:
- Metals have high density. Solid materials have a higher weight than nonmetals.
Physical forms:
- Different metals are solid at room temperatures, and mercury is liquid at room temperature.
Alloys:
- Metals mixed with other components to make alloys, which are materials with good features like high resistance to corrosion and strength.
Ionization:
- Metals lose electrons and make positive ions. Since their external electrons are not strongly connected to the positively charged nucleus and are easily removed
Properties of Nonmetals
Heat resistance:
- Nonmetals come with low melting and boiling points and need less heat for converting solid to liquid or gas.
Conductivity:
- They are not good conductors of current and heat.
Hardness:
- They are brittle and break when force is applied.
Luster:
- Nonmetals are non-reflective, dull, and have a less shiny surface.
Density:
- They are less dense as compared to metals.
Physical forms:
- They come in solid, gas, and liquid at room temperature.
Ionization:
- Nonmetals get electrons and make negative ions and anions.
FAQs
What is called a non-metal?
- Nonmetal is a chemical component that does not show features as metal has. Some gases like hydrogen, oxygen, helium, nitrogen, etc., are nonmetals.
What is called metal?
- Metals can conduct heat and electricity and can be transformed into different shapes. There are different metals that exist in periodic table elements.
What are the uses of nonmetals?
- Oxygen is a nonmetal that is used for breathing. It is important for our lives. It is also used for fuel burning at homes and vehicles for transport.
Which nonmetal is used as a fuel?
- The nonmetal used for rockets is liquid oxygen. They are hydrogen and oxygen tanks that mix and burn for starting rockets. Since hydrogen has a high calorific value, it is used.
That is a detailed post about difference between metals and non-metals if you have any query ask in comments. Thanks for reading. Have a good day.
