bromine
Just one, bromine
Metals:All metals are hard except sodiumAll metals have a high density except sodiumAll metals are solid at room temperature except mercuryNon-metals: All non-metals are insulators to electricity except graphiteAll non-metals are brittle except diamondi dont have an answer for 3 sorry! :(
At room temperature, two metals that can turn to gases are mercury and cesium. Mercury has a boiling point of 356.7°C (674.1°F) and cesium has a boiling point of 671°C (1,240°F). Both metals have low enough boiling points to become gaseous at room temperature.
all are non metals
non metals are gases and are poor conductors at room temperature
One characteristic of non-metals is that they are generally gaseous at room temperature. Non-metals will also typically bond with metals easily.
Some non-metals like carbon, sulphur, phosphorus,selenium iodine are solids at room temperature. carbon is also a solid at room temperature and even though Non-metals are not able to conduct electricity or heat very well. As opposed to metals carbon in the form of powdered graphite allowed its use as a semiconductor
Non-metals are any of the non-metallic elements found in Groups 14, 15 and 16 of the periodic table. At room temperature, most non-metals exist as either gases or solids.
Non-metals tend to have weaker interatomic forces compared to metals, leading to lower melting points. At room temperature, many non-metals have melting points below that of metals, causing them to solidify. Additionally, non-metals often have covalent or molecular structures that are more likely to be in a solid state at room temperature.
Its a gas
None of the metals are gasses at room temperature.
Non-metals are any of the non-metallic elements found in Groups 14, 15 and 16 of the Periodic Table. At room temperature, most non-metals exist as either gases or solids.
The atoms of non-metals are covalently bonded in a molecule. These molecules are joint by weak intermolecular forces of attraction which are easily overcame. Hence the boiling point is low and usually below room temperature so at room temperature, they are gaseous.
Metals: -Malleable. -Shiny -ductile -good conductor of electricity and heat. -other than mercury, all metals are solid at room temp. -not brittle. -melts at high temp. except mercury Non-metals: -non-malleable -not shiny -not ductile -poor conductor of electricity and heat -at room temp., most are gases. -melts at low temperature.
They are a good conductor of heat and electricityThey are often shinyThey are ductilethey are malleableProperties of metals include the fact that they are generally shiny, malleable, and hard.
Non-metals typically exist in solid or gas phases at room temperature, with some non-metals like iodine and bromine being in a liquid phase. Examples of non-metals in the solid phase include sulfur, carbon, and phosphorus.
