Halogens are what kind of gases?

Diatomic, but not all diatomic gases are Halogens

The Halogens are very, very reactive chemicals, and tend to hook up and form salts with the other elements rather than hanging around in a pure elemental form.  They tend to pick up extra charge very well which makes them prime candidates for bonding.

Elements with this property are called noble gases or inert gases.\n\nHelium, argon, neon, kyrpton, xenon and radon.

They're gases (although butane forms a liquid under a little pressure) and the rest are liquids, at room temperature. Pentane is highly volatile, though.

Solid or gaseous, depending on what the question means when refering to non-metals:  There are 11 gases total out of the entire table (6 are nobel gases) and only 2 liquids..mercury and bromine.  The true non-metals comprise only 7 elements, and only 3 of those (hydrogen, nitrogen, and oxygen) are gases.  If you takea  looser definition of non-metals, which includes the true nonmetals plus the halogens and noble gases, the the answer is gaseous.  From the wording of the question, I would think they were trying to get you to say gaseous.

Chlorofluorocarbons (CFC) are a group of simple alkanes (compounds of carbon and hydrogen) that also contain both chlorine and fluorine atoms.  They were widely used as propellant gases, dry cleaning solvents and refrigerants (Freon, and others).  As gases, these compounds often rise into the upper layers of the atmosphere where they react with sunlight to break down, releasing chlorine and fluorine atoms.  This process is called photodissociation.\nFree halogen atoms (such as chlorine and fluorine) react readily with ozone.  Their use over the last several decade has lead to a depletion in the ozone layer which protects our atmosphere from harmful UV radiation.  The international agreement called the Montreal Protocol is the reason that their use is prohibited.

Aargon, Helium. Noble gases are all monoatomic. Gases of Group 8 in the periodic table that is. But as you go down the group, radioactive properties start to develop, like for Radon.

More than likely a chlorine gas I would rec. NOT experimenting with the two. I work in the water treatment field. Trust me

Liquid Nitrogen: N2\n\nThe diatomic elements are hydrogen, nitrogen, oxygen, and the halogens: fluorine, chlorine, bromine, iodine, and astatine. Astatine is so rare in nature (its most stable isotope has a half-life of only 8.1 hours) that it is usually not considered. Many metals are also diatomic when in their gaseous states.\n\n\n\nIn inorganic chemistry, the bisulfite (IUPAC-recommended nomenclature: hydrogen sulfite) ion is the HSO3− ion. It is the conjugate base of sulfurous acid, H2SO3. Salts containing the \nHSO3− ion are bisulfite [salt]s It is a weakly acidic substance which has a pKa of 6.97.\n\nSilver Bisulfate: AgHSO3\n\n\nPotassium Phospate (tribasic): K3 P O4 \n\nhttp://www.hbci.com/~wenonah/hydro/2kpo.htm

INERT GASES\nNOBLE GASES\nRARE GASES\nALL are names given for atoms(not elements) that are unreactive.\nThese  belong to 8 th group of periodic table and they are\nHe,Ne,AR,Kr,Xe,Rn\nThe above names are given because they are highly stable and unreactive. \nActuallly u should not call them elements because they do not form elements and exixts in atomic state because of high stability.

H2S.  That's very similar to H2O (which we usually associate with H-Bonding).  HBr, HCl, and HF will ionize.  SiH4 is symmetric and Si has medium electronegavity, etc, such that it would be like methane (Si is in the same group as C).

Cl is an halogene, like F or Br.  They all have the properties to kill germs (Cl in pool water, F in toothpaste, Br in surgical antiseptics).

Halogens, in their elemental state, are covalent. In their elemental state, they are not compounds, because they are not combined with other elements. But F2, Cl2, Br2, I2, and At2 are covalently bonded.

Solid. Most elements at standard atmospheric temperature and pressure are solids. Some of the non-metals are gases, but only Mercury and Bromine are liquids at STP.\n\nEDIT: Gloo-gal, why answer if you don't know or don't care?
