Non-metals are such elements which have 4,5, 6 and 7 electrons in their outermost shell. Examples of non-metals are carbon, oxygen chlorine etc. Metals are such element which have generally 1,2,3 valence electrons. .

It does not follow the law of reflection. Lustrous material are bright in appearance. Non – Lustrous material are dull in appearance. The lustrous metals like gold and silver are mostly used to make jewellery. Non – lustrous material are not used to make jewellery. The examples for the lustrous Materials are gold, silver, copper, iron.Nonmetals. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle .

1. Dull. Generally, non-metals are dull in nature. This property of non-metal is called non-lustrous. Exception: Iodine is shiny in nature. 2. Soft and Brittle. Non–metals are brittle in nature and can be broken by beating them with a hammer or with any hard substance. Exceptions: Diamond is the hardest material.A nonmetal is an element that is generally a poor conductor of heat and electricity. Most properties of nonmetals are the opposite of metals. There is a wider variation in properties among the nonmetals than among the metals. Nonmetals exist in all three states of matter. The majority are gases, such as nitrogen and oxygen.non lustrous metal namesQ. Question 30. Non-metals are usually poor conductors of heat and electricity.

(c) The allotropic form of a non-metal is a good conductor of electricity. Name the allotrope.Nonmetals. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids.

Here is a summary of the properties of the nonmetals. High ionization energies. High electronegativities. Poor thermal conductors. Poor electrical conductors. Brittle solids—not malleable or ductile. Little or no metallic luster. Gain electrons easily. Dull, not metallic-shiny, although they may be colorful. There are only. 2 2. elements that are non metal but having a property of lustre. Complete step by step solution: Lustre is basically a property of minerals that how well the mineral reflects light. The two non metals having lustre is Diamond and iodine. In diamond due to conduction of heat, they are cold and are at room temperature.

Exceptions in Physical Properties of Non-Metals. Unlike other non-metals, graphite and iodine have metallic lustre or shine. Carbon although being non-metal has a high melting point. Bromine is found in a liquid state at room temperature just as mercury. Iodine is a non-metal with a density of 4.9.

In metals, it is a gentle light that shines due to reflection of light, for example Gold is a metal that can be lustrous for a long period of time. Generally, most of the non- metals does not have lustrous property. But, Iodine is a non- metal which have lustre and is lustrous in nature.For performing Activities 3.1 to 3.6, collect the samples of following metals – iron, copper, aluminium, magnesium, sodium, lead, zinc and any other metal that is easily available. Activity 3.1. n Take samples of iron, copper, aluminium and magnesium. Note the appearance of each sample. Metals vs Nonmetals. Elements may be classified as metals, nonmetals, or metalloids. Elements with some characteristics of metals and some of nonmetals are metalloids. Metals are on the left side of the periodic table. Nonmetals are on the right side of the table. Metalloids occur in zig-zag line on the table, separating metals and . Example – Sodium metal reacts with water and forms sodium hydroxide and hydrogen gas. The reaction is given below . Non-metals are not lustrous which means they are not shiny. Instead of dull in appearance. Non-metals have low tensile strength. It .

Nonmetals. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids. These properties differ from metals to non-metals but are usually quite similar in groups due to elements being grouped based on their similar physical and chemical properties. For example, all group 1 metals are soft metals and they can float on water as they are less dense than water.
