Which of the following is a non metal

Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorous, sulphur, silicon, boron, tellurium and selenium. They also include halogens (fluorine, chlorine, bromine, iodine and astatine) and noble gases (helium, neon, argon, krypton, xenon and radon).

Which of the following is non not a metal?

Hydrogen, carbon, nitrogen, oxygen, chlorine, etc are non-metals, whereas sodium is a member of the alkali metal group. So, sodium is not a non-metal.

Which of the following is a non-metal Zn Al Fe Cl?

Answer. Explaination: Cl is non-metal because it is a halogen.

Which of the following is a non-metal Class 8?

Name some common non-metals. Answer: Hydrogen, oxygen, carbon, sulphur, phosphorus, etc.

What are the 20 nonmetals?

Metals in the first twenty elements are Lithium, Beryllium, Sodium, magnesium, Aluminum, Potassium, and calcium. Now the non-metals in the first twenty elements are Hydrogen, Helium, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Phosphorous, Sulphur, Chlorine, and Argon.

What are the 10 examples of non-metals?

In the above table nonmetal elements are H,He,C,N,O,F,Ne,P,S,Cl,Ar,Se,Br,Kr,I,Xe,At and Rn.

What is non-metal Class 7?

Non-metals are those which lack all the metallic attributes. They are good insulators of heat and electricity. They are mostly gases and sometimes liquid. Some they are even solid at room temperature like, Carbon, sulfur and phosphorus.

Which one is not a metal or nonmetal?

The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.

How many non-metals are there?

Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

Why Cl is a non-metal?

Chlorine is a non-metal. Elemental chlorine is a bimolecular gas under normal conditions. It usually accepts electrons so is an oxidant. ie., a typical property of a non-metal.

What is the non-metal group?

The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium. Hydrogen acts as a nonmetal at normal temperatures and pressure and is generally accepted to be part of the nonmetal group. The halogens are nonmetals in group 7 of the periodic table.

Which of the following is a non-metal choose the correct answer?

The correct answer is Nitrogen.

What is non-metal Class 4?

Non-metals may be of solids, liquids, or gases. Except for Graphite, non-metals are poor conductors of heat and electricity. They don't possess metallic lustre. Non-metals do not produce a ringing sound and are not sonorous. Non-metals possess no malleability and are not ductile.

Is Group 8 a non-metal?

Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). They are all transition metals.

What are 17 non-metals?

The 17 nonmetal elements are: hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, and radon.

Are there 22 non-metals?

In modern periodic table there are 22 non-metals in which there are 11 gases, 1 liquid and 10 solid. Bromine occurs in the state of liquid and hydrogen, nitrogen, oxygen, chlorine etc are found in gaseous forms. But carbon, sulphur, phosphorous, iodine etc solid non-metals.

What is non-metal Class 6?

A non metal is a material which do not have properties of metals like lustre. They are non malleable, non ductile, non sonorous and bad conductor of heat and electricity. Example- Carbon, Sulphur, Phosphorous.

What are the 16 non-metals?

Selenium.
Fluorine.

What is non metal answer?

In chemistry, a nonmetal is a chemical element that generally lacks a predominance of metallic properties; they range from colorless gases (like hydrogen) to shiny solids (like carbon, as graphite). The electrons in nonmetals behave differently from those in metals.
