Oh, dude, HOFBrINCl is just a fancy way of saying "hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, and chlorine." It's like the cool kid version of the Periodic Table elements. So, if you ever need to sound super smart at a chemistry party, just drop the HOFBrINCl bomb and watch everyone nod like they totally know what you're talking about.
Chlorine is an element, but chlorine gas in it's pure state is a diatomic molecule, meaning it is two of the same atom covalently bonded. all halogen gases do this, plus a couple others. A good way to remember this is HOFBrINCl. Hydrogen, Oxygen, Florine, Bromine, Iodine, Nitrogen, and Chlorine. All of them ARE NEVER alone in their pure form, they are always diatomic.
Hydrogen gas is a colorless, odorless, and tasteless gas at room temperature. It is highly flammable and burns with a clean, blue flame. Hydrogen is the lightest element, and it has the lowest density of any gas.
HOFBrINCl is a mnemonic for remembering the diatomic elements: Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, and Chlorine, which exist naturally as pairs of atoms bonded together. This can be useful when studying chemistry to remember which elements are diatomic.
Two non-metals, such as carbon and oxygen, as well as HOFBrINCl (google it) and many others.
The elements in HOFBrINCl (hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, chlorine) form covalent bonds due to their high electronegativity values, which result in sharing electron pairs in order to achieve stable electron configurations. These elements have similar electronegativities, making covalent bonding preferable over ionic bonding.
My chemistry teacher always taught us Dr. HOFBrINCl H-Hydrogen O-Oxygen F-Fluorine Br-Bromine I-Iodine N-Nitrogen Cl-Chlorine
Nitrogen, in its natural state is a gas. Being of a diatomic nature (existing in pairs of twos), it will be N2(g). Remember HOFBrINCl Hydrogen, oxygen, etc.. (above mentioned atoms) ALL exist in a diatomic nature. Remember this patter by saying ... "hof-brincl"
Atoms that bond themselves into pairs are called diatomic molecules. Some examples include hydrogen (H2), oxygen (O2), nitrogen (N2), and chlorine (Cl2). Each atom in the pair shares electrons to form a covalent bond, creating a stable molecule.
Chlorine is an element, but chlorine gas in it's pure state is a diatomic molecule, meaning it is two of the same atom covalently bonded. all halogen gases do this, plus a couple others. A good way to remember this is HOFBrINCl. Hydrogen, Oxygen, Florine, Bromine, Iodine, Nitrogen, and Chlorine. All of them ARE NEVER alone in their pure form, they are always diatomic.
HOFBrINCl are all atoms that are found as diatoms when in their natureal gaseous state. This means that they are gasses when at room temperature, but the individual atom are not found alone. Rather, they are found in groups of two. (ex. N2) because they are more stable that way.
Hydrogen, nitrogen, oxygen, and the hallogens.
It's easiest to remember the acronym HOFBrINCl (pronounced "hoffbrinkle") when you're memorizing diatomic molecules. Just remember that each element's symbol is included in the acronym, not just the first letter of the element's name.HydrogenOxygenFluorineBromineIodineNitrogenChLorineor use:Never - NitrogenHave - HydrogenFear - FluorineOf - OxygenIce - IodineCold - ChlorineBeer - BromineHelium isn't part of this list, so no, it is not diatomic. It is definitely too inert to regularly form diatomic molecules with itself, although someone managed to make it bond with itself at very, very low temperatures. Even then, the two atoms were separated by an entire arm's length...Blurb on "diatomic" He: http://www.aip.org/pnu/1993/split/pnu118-2.htmHope this helps!
You can easily remember the formulas of the homonuclear diatomic elements using the saying Never Have Fear Of Ice Cold Beer. This stands for N2, H2, F2, O2, I2, Cl2, and Br2.
Common diatomic molecules can be remembered using the anagram HOFBrINCl (Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, Chlorine). Diatomic molecules don't have to be composed of only one type of element (homonuclear). Carbon Monoxide (CO) is also an example of a diatomic molecule.
