The halogens are fluorine, chlorine, bromine, and iodine. They all share the chemical property of having 7 valence electrons. In order to satisfy the octet rule of 8 outer energy level electrons, 2 halogens must share a pair of electrons. This bonds them together with a single covalent bond.

What is the name of substance f2?
If you mean the name of the element with the symbol F, it is Flourine
Why atomic hydrogen is more reactive than hydrogen gas?
Hydrogen gas at standard temperature and pressure exists as diatomic molecules, and much of the chemical potential energy of atomic hydrogen has been evolved as heat along with forming the diatomic molecules.
Is bromine gas an atomic element?
Under most readily achieved temperature and pressure conditions, bromine gas exists as diatomic molecules. Bromine is always an element.
What type of gas is in a tungsten-halogen light bulb?
Halogen gas is in a Tungsten-Halogen Light Bulb.
What gas is a halogen filled with?
Halogen is a gas, so your question doesn't make much sense. If you're asking about a halogen (light) bulb, then the answer is: mainly halogen.
Does hydrogen exist as a diatomic?
Yes, hydrogen gas exists as a diatomic molecule with the formula H2.
Is hydrogen mono atomic?
No. Hydrogen exists as a diatomic gas.
What is hydrogen fuel's chemical formula?
hydrogen + oxygen → water 2H2 + O2 → 2H2O Hydrogen gas exists as diatomic molecules, H2 and oxygen gas exists as diatomic molecules, O2
What are the properties in chlorine?
At room temperature it is a pale green gas. When dissolved in water it becomes clear/pale green A diatomic molecule which has a very low Melting and boiling point. It is described as a halogen because it is found in group 7
Is gas green?
Green gas is a halogen, which you will find in the periodic table. It is in group seven. It is the Chlorine
Is hydrogen like plasma?
NO!!!! Hydrogen exists as a diatomic gas. (H2 ( H-H) ).
What is the gas with a mass number of nineteen?
The atomic mass 19 is for fluorine, the ist member of halogens it exists as F2,a diatomic gas.
Is nitrogen gas monatomic or diatomic?
Nitrogen gas is diatomic.
How do halogen molecules exist?
Halogens are considered to be diatomic molecules. They exist in gas (F2, Cl2), liquid (Br2) and solid phase (Iodine I2).
What is the name of substance f2?
If you mean the name of the element with the symbol F, it is Flourine
Is He2 joined by a double covalent bond?
He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)
What do oxygen molecules contain?
Molecules of oxygen contain 2 oxygen atoms. Oxygen is a diatomic gas, meaning that it exists in pairs of atoms when in pure gas form. Other diatomic gasses include hydrogen and nitrogen.
