Which elements are solid at room temperature?
Hydrogen, Oxygen, Nitrogen, Helium and all of the Noble Gases, Fluorine, Chlorine, Bromine, Mercury.
Originally Answered: What is the example of the solid at room temperature?.
What are the 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 are the solid nonmetals?
Among the strict nonmetals groups, the only solids are carbon, phosphorus, sulfur, selenium, bromine, and iodine.
What are the 11 non metals?
Hydrogen, hydrogen, chlorine, fluorine, carbon, nitrogen, arsenic, phosphorus, selenium are examples of non-metal.
Why Oxygen is a non metal?
Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon).
Are metals brittle?
The traditional definition focuses on the bulk properties of metals. They tend to be lustrous, ductile, malleable, and good conductors of electricity, while nonmetals are generally brittle (for solid nonmetals), lack lustre, and are insulators.
Is Lead heavier than gold?
Gold is much heavier than lead. It is very dense. … Therefore gold weighs 19.3 times as much or (19.3 x 8.3 lb) about 160 pounds per gallon. Although gold has a density 19.3 times greater than water and is one of the most dense substances on Earth, there are substances with far more amazing densities.
What is the hardest metal element?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi).
How many solid nonmetals are there?
There are eighteen nonmetals.
Which elements are solid nonmetals at room temperature?
Solid Nonmetal Elements The remaining elements, carbon, phosphorus, sulfur, selenium, and iodine, exist in solid forms at room temperature.

Which is the lightest non metal?
Helium gasHelium gas is only twice as heavy as hydrogen gas. But as hydrogen shows properties of both metals and non-metals it has a special position in periodic table. So taking that into consideration He is the lightest non-metal.
What is the heaviest non metal?
IodineIodine has a mass of 126.9 which makes it the heaviest listed non metal.

Is oxygen a metal or nonmetal?
Group 16 of the periodic table is also called the oxygen group. The first three elements—oxygen (O), sulfur (S), and selenium (Se)—are nonmetals. They are followed by tellurium (Te) (Figure below), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive.
