Most nonmetals are not liquid at room temperature, as they are gasses. The only nonmetal that is in a liquid state at room temperature is bromine.
Yes, in solid form nonmetals tend to be brittle, however, several nonmetals are gasses and one, bromine, is a liquid.
No, most nonmetals are not ductile. Ductility is the ability of a material to deform under tensile stress before breaking, and nonmetals typically lack this property due to their atomic structure and bonding characteristics.
No. In fact the only non-metal that is a liquid at room temperature is Bromine, and even that can be considered a gas at times. The only other liquid in the periodic table is Mercury, which is a metal.
No, nonmetals are not invisible. Nonmetals such as oxygen, nitrogen, and carbon are visible in their gaseous form as they make up the air we breathe. Other nonmetals like sulfur and iodine can be seen in their solid or liquid forms.
Everything that you touch is MATTER. You are matter. So solids, liquids and gases are matter. It follows that non-metals are matter. NB THere are only two liquid elements in the periodic table, they are bromine and mercury.
Some are solid (eg carbon) some are gaseous (eg oxygen) and one is liquid (bromine).
Most non-metallic elements are gases. They include all the noble gases (group 18), fluorine and chlorine in group 17, oxygen, and nitrogen. Under normal, familiar conditions, bromine is a liquid, and sulfur, selenium, phosphorus, and iodine are solids. Anything not mentioned is either a metal or a metalloid.
Bromine is the only nonmetal that is a liquid at room temperature and pressure. It is also the only nonmetal that exists as a diatomic molecule in its pure form (Br2), whereas most nonmetals exist as single atoms. Additionally, bromine has a higher atomic number and larger atomic radius compared to other nonmetals like oxygen, nitrogen, and carbon.
Nonmetals can be solid, liquid or gaseous.
Yes.
Metals: alkaline metals Nonmetals: halogens
The most reactive nonmetals are the Halogens. They are located in the second to last row on the Periodic Table from the right.
