Since noble gases and halogens are also non metals these elements are often referred to as non metals.
Non metal elements that are solid at room temperature.
One non metal bromine is a liquid at room temperature.
Properties of non metals.
Bromine is the only non metal and mercury only metal liquid at room temperature now the question arises why there is not really any deeper answer like mercury has a special electron configuration that means the bonds between the mercury atoms.
Elements that come under non metals are sulphur carbon all halogens phosphorus hydrogen oxygen selenium nitrogen and noble gases.
Non metals may exist in solid liquid or gaseous state at room temperature.
Elements that are liquid at 25 c.
Carbon is also a solid at room temperature and even though non metals are not able to conduct.
Non metals are insulators or poor conductors of electricity and heat because they do not lose electrons to transmit the energy.
They are non sonorous.
Mercury is the only metal that is always liquid no matter the temperature.
Eleven non metals are gases at room temperature including oxygen and chlorine.
In the periodic table non metals are located left of the halogens and to the right of the metalloids.
For science it s usually considered to be either 20 c or 25 c.
Some non metals like carbon sulphur phosphorus selenium iodine are solids at room temperature.
Nitrogen and oxygen are gaseous non metals.
The only exception to this property in fact is mercury.
Generally the melting point of metals is high.
Most metals have a solid state when they are at room temperature.
They are mostly gases and sometimes liquid.
Room temperature is a loosely defined term that can mean anywhere from 20 c to 29 c.
So it stays at a liquid stay even at room temperature.
They are good insulators of heat and electricity.
Solid liquid or gas at room temperature.
The other non metals are solids at room temperature.
For example carbon sulphur and phosphorus are solid at room temperature.
Some they are even solid at room temperatures like carbon sulphur and phosphorus.
They can be transparent.
At this temperature and ordinary pressure only two elements are liquids.
At room temperature they can be in the state of solids liquids or gases.
Bromine is a non metal which is liquid at room temperature.
Non metals are those which lack all the metallic attributes.
