Sharing electrons
Yes, most molecular compounds do not contain metals. (The term "nonmetal" properly applies only to elements, not compounds.)
very few compounds of either metals or nonmetals are gasses at room temperature.for example lets look at the oxides of semiconductors:carbon - CO2, gassilicon - SiO2, solidgermanium - GeO2, solid
When group 1 elements (such as lithium, sodium, potassium) react with nonmetal elements, they typically form ionic compounds. These compounds consist of a metal cation from the group 1 element and a nonmetal anion, resulting in salts like lithium chloride (LiCl), sodium fluoride (NaF), or potassium iodide (KI).
No, ammonia is not a binary acid. Binary acids are compounds composed of hydrogen and one other element, usually a nonmetal. Ammonia is a compound made up of nitrogen and hydrogen, so it is not a binary acid.
It is not an element... for hard water usually a build up calcium compounds.
non-metals are normally prittle, with one important exception being complex organic compounds like rubber.
Plastic is usually a nonmetal material.
Vanadium is found i compounds and iron alloys.
These are characteristics of solid nonmetal elements.
Molecular compounds are typically made up of nonmetals. Metals tend to form ionic compounds with nonmetals, whereas nonmetals tend to share electrons with other nonmetals, resulting in the formation of molecular compounds through covalent bonding.
It depends on the nature of the metal-nonmetal compound formed. Metal-nonmetal compounds, known as ionic compounds, are usually poor conductors of electric current in solid state due to the lack of free-moving electrons. However, when dissolved in water or melted, they can conduct electricity due to the presence of mobile ions.
Oxides are the type of compound that is typically formed when an element is burned in air. Oxides are compounds composed of an element combined with oxygen.
