A chemical compound, solid, may contain many nonmetals.
Probable neptunium with a density 0f 20,45 g/cm3; the density of chemical elements with greater atomic numbers is rarely known.
Bromine is the only nonmetal element that is a liquid at room temperature.
there are only one solid nonmetal: Bromine
this answer is the element Bromine.
Carbon (C)
Group 4 (Now 14) of the Periodic Table contains only one non-metal; Carbon (C). All the rest of the elements in this group are metals. The metals in Group 4(14) are;SiliconGermaniumTinLead
Potassium fluoride only contains the elements potassium and fluorine. Potassium is an alkali metal. Fluorine is a halogen, which is a type of nonmetal.
The only metal element to exist in a non-solid state at room temperature is Mercury, which is a liquid between -38.83 °C and 356.73 °C at standard pressure.
Group 3a (13) on the periodic table contains boron which is considered a metalloid. The other elements in the group are post-transition metals.
A substance that only contains one kind of atom is called an element.
The element that can exhibit properties of both a metal and a nonmetal is called metalloid. Examples include silicon, germanium, and arsenic. Metalloids have properties that are intermediate between metals and nonmetals.
Gold is an element so it only contains the element, gold.
