Any element that is not a metal is, by definition, a nonmetal. These come in basically two types, the chemically active nonmetal and the inert nonmetal. Sulfur, oxygen, nitrogen, carbon, silicon, phosphorus, and the halogens, fluorine, chlorine, bromine, iodine, and astatine, are the most important of the chemically active nonmetals; hydrogen is an ambiguous element since it can be either a metal or a nonmetal, although it is usually a nonmetal (note that at low temperature and high pressure, hydrogen actually will become a metallic solid, with all the usual features of a metal, even though under more usual temperatures and pressures it is a transparent gas bearing no resemblance to a metal). The inert nonmetals are the noble gases, helium, neon, krypton, xenon, and radon.

What is a compound containing three elements including at least one metal?
There are many kinds of compounds, and not all of them have both metal and nonmetal types of atoms in them. Carbon dioxide, for example, is composed of two types of nonmetal atoms.
What are covalent bonds formed between?
Metal atoms.
What are facts about covalent bonds?
nonmetal with nonmetal pair of electrons is shared between 2 atoms
What rule do the nonmetal atoms follow?
octet rule
What kinds of elements are involved in an ionic bond?
In most cases the types of elements that are involved in ionic bonding are a metal and a nonmetal. for example: NaCl , KI and some more.
An oxyanion is one or more oxygen atoms bonded to?
A Nonmetal.
In chemical compounds covalent bonds form when -?
when.... 1- a metal forms bond with metals. 2- a nonmetal with nonmetal nonmetal. 3- or atoms having electronegativities difference less than 1.7 (with exeption of HF having E.N diff. 1.9)...... or Jefferson lab says: when pairs of electrons are shared between two nonmetal atoms or when pairs of electrons are shared between two nonmetl atoms
When nonmetals react with other nonmetal the atoms of the nonmetals?
The nonmetals share the atoms when reacting with each other.
If atoms of a halogen nonmetal gain one electron the atoms the have?
They become anions, with negative electrical charge.
How are atoms held together in molecules?
Various things. If it is a nonmetal and nonmetal it going to be a covalent bond. If it is a metal and nonmetal it is going to be an ionic bond. If it is a metal and metal then it is a metallic bond.
How many electrons will the metal sodium atoms lose when the metal reacts with a nonmetal?
Sodium loses one electron when it reacts with a nonmetal.
What compound develops when nonmetal atoms chemically combine?
These are covalent compounds.
