5] Graphite is used as a good conductor of electricity. Of the alkali metals, only lithium reacts with nitrogen, and it forms a nitride (Li 3N). In general, one could define a metal as being a material having these properties: Luster, malleability, ductility, excellent thermal and electrical conductivity, and opacity. Example 2: A metal such as iron – two allotropes of iron are austenite and ferrite Have a look at the given table depicting the major Difference Between Metals And Nonmetals for better understanding. All these alloys share the same two basic non … 7] Nitrogen is used by plants. 2] Chlorine is used for purifying water. You should notice that there are more metals then non-metals. The group of elements that are poor conductors of heat and electricity are called NONMETALS. Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Examples of nonmetals include: hydrogen, carbon, and nitrogen. They are especially studied under the subject of inorganic chemistry. Some non - metals and their uses are listed below - 1] Oxygen is used for breathing. Metals and Non Metals.We’ll discuss the most important topics asked in the CBSE Board exam to maximize your marks in the minimum amount of time. Metals are found on the left of the line, and non-metals are those on the right. Non-metals are defined as the elements which easily form negative ions by accepting electrons and do not conduct heat and electricity. Magnetic or non-magnetic Copper coin Non-magnetic 10. The nonmetal elements occupy the upper right-hand corner of the periodic table. The zigzag line separates all the elements that are metals from those that are non-metals. 3] Phosphorous is used in crackers. Besides, metals like titanium, aluminum, magnesium are widely used in medicine for roles like antacids. All nonmetals form covalent oxides with oxygen, which react with water to form acids or with bases to form salts. 5] Graphite is used as a good conductor of electricity. The non-metals are either solids or gases except bromine which is a liquid. Metals are found on the left of the line, and non-metals are those on the right. Metals, metalloids and non-metals all have their own specific properties. are very soft metals, these can be cut using knife. Some metals have specific qualities that dictate their use. Non-metal does not react with water but it is usually very reactive in air, which is why some of them are stored in water. Along the line you find the metalloids. 6] Pottassium is used in fertilizers. 4] Non - metals like nitrogen is used in fertilizers. Magnetic or non-magnetic silver coin Non-magnetic 11. These elements are distinctive in that they typically have low melting and boiling points, don't conduct heat or electricity very well, and tend to have high ionization energies and electronegativity values.
