Non-metals do not show ductility and malleability. Metalloids neither possess a too high or too low value of electronegativity. Thermal and electrical conductivity is good though it is less than metals. Thermal and electrical conductivity is high in metals. Metalloids have a shiny and dull appearance. Metalloids are placed in the middle of the periodic table. Non-metals are placed on the right side of the periodic table. Metals are placed on the left side of the periodic table. Metalloids are such elements, which possess some of the properties like metal, while some like non-metal. Non-metals are such elements which do not possess any metallic behaviour. The metals which exhibit the highest degree of metallic behaviour is known as metals. Content: Metals Vs Non-Metals Vs Metalloids We will also provide a summary of them with examples. In this content, we will apparently discuss the point on which metal, non-metals, and metalloids differ. The arrangement of the elements in the periodic table share such information from one to other, left to right, top to bottom. Therefore, it has been observed that the elements share these properties with one or the others and on the ground of which they are been categorized in three classes, viz are metals, non-metals, and metalloids and are fixed in the periodic table. Burning, rusting, tarnishing are the kinds of chemical properties. The chemical properties shows the inherent nature of the element, how they will react when combined with other elements to form compounds. Physical properties like colour, hardness, type of existence (solid, liquid or gas) and their shine (luster), or those characteristics which can be observed without any chemical reactions. Each element acquires certain physical and chemical properties. Till now there are more than 100 elements have been found in nature, and it is believed that their number can exceed. ![]() We often find neon used in signs as it is coloured when electricity is put through it.Tin, iron, plutonium, and sodium are some of the examples of metal, chlorine, oxygen, and argon are some of the non-metals, while boron, arsenic, and silicon are the names of some of the metalloids.Īll types of matter are composed of the atoms of the various elements. These gases are quite special, when a high amount of electric energy is put through them they will give off a coloured light. The Halogens are next to group 18, the noble gases these are non metal gases that are very unreactive and are all gases. A common gas in group 17 is chlorine which is used to kill bacteria and clean swimming pools, it has a strong smell. A larger atom in the non-metals produces stronger attractions meaning the states change from gas to liquid to solid progressing down Group 17. Progressing from Fluorine to Chlorine both gases to Bromine, a liquid to Iodine a solid. Group 17 the Halogens contains a range of non-metals but a key trend can be seen. Nitrogen is also found in the air and is important for plants an animals to grow. Carbon is found in a lot of living organisms as a compound with other elements, it is also used as coal in power stations. Oxygen is in the air and is important to us when we breathe and for respiration. Some elements in these groups you will be familiar with are oxygen, nitrogen and carbon. Metals also tend to be shiny and silver coloured where as non metals tend to be coloured and sometimes dull. Non metals in this part of the periodic table tend to be liquids and gases and are brittle, when they are hit they break apart and shatter. These non metals have very different properties to metals, they do not tend to barde shiny and wont conduct heat or electricity well. For example Group 15 contains the non-metals Nitrogen and Phosphorus, the semi-metal Arsenic and the metals Antimony and Bismuth. They are often used in buildings and for making strong materials as they are heavy and hard.įrom Group 13 to 16 these are a mixture of metals, non-metals, and semimetals. These have characteristic properties and are less reactive. ![]() The next part of the periodic table is the transition metals from group 3 to 12. They also have similar reactivity with Group 1 being much more reactive than Group 2. Group 1 alkali metals, Group 2 Alkaline earth metals are both named as such as often they form alkalis. Metals are predominantly located on the left of the periodic table. There are of course some exceptions to this. Most metals are solids and non-metals are liquids and gases. ![]()
