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 names of the groups of nonmetals?

Groups of Nonmetals 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.

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 are the families containing nonmetals?

In general, most nonmetals are poor conductors of electric current and heat. Solid nonmetals tend to be dull and brittle. Describe the families that contain nonmetals (4) The families containing nonmetals include the carbon family, nitrogen family, oxygen family, halogen family, noble gases, and hydrogen.

What are some examples of nonmetals and their uses?

Nonmetals typically are poor electrical and thermal conductors, without a metallic luster. They may be found as solids, liquids, or gases under ordinary conditions. Examples include: nitrogen. oxygen. helium. sulfur. chlorine.

What are the different types of nonmetals?

Nonmetals include the noble gases, The halogens (Chlorine, fluorine etc ) The Chalcogens (Oxygen Sulfur Selenium etc), The Nitrogen group (Nitrogen, phosphorus etc) The Carbon Group with silicon etc, The Boron group.

Which group contains only nonmetals?

Group VIIA is the only group in periodic table in which all the elements are nonmetals. This group contains F, Cl, Br, I and At. The other name of this group is halogen which means salt producer.
