Prefixes are used to tell how many of each kind of atom are in covalent compounds. - APEX
You add prefixes ONLY to covalent. For ionic, just add the suffix -ide.
Because the rules of nomenclature say so.
Unlike ionic compounds, which are known to transfer electrons in specific numbers from metal to nonmetal, covalent compounds can often share electrons in many different arrangements. For example, nitrogen and oxygen can share electrons to form many different compounds, requiring prefixes to distinguish them: N2O NO NO2 ...etc...
The same atoms can combine in more than one ratio.
Firstly C3H6 is not an ion it is an alkene, called propene or propylene, or alternatively it is a cyclic hydrocarbon called cyclopropane. Greek prefixes are used for pentane (C5 compounds) and above. Ion? I am not sure what is being asked.
Covalent compounds are neutral. Covalent compounds share electrons.
mono, di, tri, tetra, pent, hex, hept, oct, nona, dec.
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
Organic compounds have covalent bonds, and these compounds are the basis of life on Earth; the human body is composed of them.
As the name implies, it is made of one sulfur atom and three oxygen atoms. Its formula is SO3. For covalent compounds such as this, the rules of nomenclature require prefixes, unless the first constituent element (sulfur, in this case) has only one atom per molecule. Then there is no prefix. This is why it's not "monosulfur trioxide." However, if the second constituent element has only one atom per molecule, the prefix "mono-" is used… Read More
Aluminum oxide is an ionic compound. Prefixes are not used in naming ionic compounds, but are used in naming binary molecular compounds.
yeah.. mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10 dodeca-20 The real answer is NO. The prefixes are only used in Type III compounds which are Covalent Bonds. Ionic Bonds only need the ending -ide.
1: mono (but only used for the second element) 2: di 3: tri 4: tetra 5: penta 6: hexa 7:hepta 8: octa 9: nona 10: deca
I assume you're talking about prefixes in chemistry. When naming covalent, or molecular compounds, prefixes are necessary because there are different ways that the non-metals can bond with other non-metals. Here are the prefixes most often used in covalent compounds: mono=1 di=2 tri=3 tetra=4 penta=5 hexa=6 hepta=7 octa=8 nona=9 deca=10. For example, N2O4 is "dinitrogen tetroxide." *A noteworthy exception: if there's only one of the first atom, you DON'T use the mono-prefix; you simply don't… Read More
It is used to form molecules and various compounds. In fact, most of the bonds are covalent bonds.
ionic and covalent bonds
Scientific prefixes are used for multiple/submultiple of units of measure, names of chemical compounds, name of chemical methods, instruments, etc.
Quadri (Latin) and Tetra (Greek) are both prefixes used for the number 4
This compound is covalent as evidenced by the lack of a metal in the compound. Therefor the covalent system system of naming is used. In that system greek prefixes are used to indicate the number of each element in the compound. The prefixes in order are mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca. Using this method the correct name of the element is monophosphorus tribromide, however convention allows the dropping of mono… Read More
They are named using different rules than those used to name ionic compounds.
two ions can combine in only one combination
The first five prefixes used in molecular compounds are: 1 mono-, 2 di-, 3 tri-, 4 tetra- and 5 penta-.
The formula for dicarbon dehydrate is C2H2. Remember that the prefix di means two and the rules for naming covalent compounds. First element is named using its name. The second is named as an aniond with the suffix -ide. Prefixes are used to denote the number of atoms of each element, except for mono.
Ate, and Ite. Theres also ide but just depends =]
The formula mass is used to express the mass of ionic compounds and molecular mass for the molecules or covalent compounds.
ortho- (1,2), meta- (1,3) , para- (1,4)
Electrolyte is the solution that is used to conduct electricity and acts as a medium to liberate certain ions in the electrolytic cell. The electrolyte must be an ionic compound or a polar covalent compound because all electrolytes are in aqueous solutions. Not all covalent compounds can dissolve in water because it is a polar solvent. Only specific covalent compounds can dissolve in water, they include hydrochlorine, which forms hydrochloric acid when dissolved in water.
The Answer is DI
Usually ionic compounds are electronegative.
There are hundreds of prefixes and suffixes from the Greek language that we use everyday. Most of them are used in the medical field such as bio- and branchi-.
Because some covalent compounds have more then one valid Lewis dot structure
There are two types of atomic bonds used when forming compounds. There are ionic and covalent, depending on how each atom's electrons interact.
Covalent compounds are generally not good conductors because the electrons are not free to move. Solid ionic compounds are generally not good conductors because the ions are not free to move as they are locked in place in a lattice (this is not true when ionic compounds are molten or in solution!) As always there are a few exceptions, graphite is covalent but the electrons are delocalised and it does conduct, there are also a… Read More
A suffix -ide is used to indicate a covalent compound of only two elements. It is not applicable to all covalent compounds. Examples include the compounds of carbon and oxygen. Carbon monoxide (CO) and carbon dioxide (CO2). If you would like to check the reliability of my information my source was Bill W. Tillery's college text book "Physical Science." The information can be found on the lower half of page 263, chapter nine in the… Read More
If you're speaking of Greek prefixes like poly- or mono-, then it'd either be a- or an-. The latter prefix is used if a vowel is immediately followed.
pretty much all are covalent bonds, C-C is covalent bond, C-H, C-O, C=C, C~C, C-N, C=N, C~N are all covalent bonds. Most polymers have just a carbon backbone, thus covalent. I can not think of an ionic bonded polymer, some of the regents used to make polymers can be ionic like salts, but the final chain of mers is covalent, typically non-polar.
1- Mono 2- Di 3-Tri 4- Tetra 5- Penta 6- Hexa 7- Hepta 8- Octa 9- Nona 10-Deca
Mono one; di- two; tri 3; tetra, 4; penta 5; hexa, six; hepta, 7; octa, 8; nona, 9; deca, 10
Molecular. If you compare the electronegativities of phosphorus and chlorine, the difference between them falls in a spectrum of molecular compounds. The quick and easy answers : 1) non metals only = molecular. 2) the prefixes in the name (tri =3, penta=5) are used for the naming of molecular compounds (and hydrates)
In most cases it forms covalent compounds as the silicon atom has four valence electrons in outer shell. Silicon forms binary compounds called silicides with many metallic elements whose properties range from reactive compounds, e.g. magnesium silicide, Mg2Si through high melting refractory compounds such as molybdenum disilicide, MoSi2. In quartz each silicon atom is surrounded by four oxygen atoms that bridge to other silicon atoms to form a three dimensional lattice. Pure, crystalline silicon dioxide… Read More
Both mean having one of something. But uni- comes from the Latin, and is most often used with Latin-derived words: unicycle, unicorn. Whereas mono- comes from the Greek, and is best paired with Greek-derived words: monocle, monogamy.
Ionic compounds, as the name implies, are made up of positive and negative ions. The bonding in ionic compounds is based mostly on the electrostatic attraction between the cations and anions rather than from the sharing of electrons. No bond is totally ionic; there is some covalent character in every bond. The term "Formula Unit" is used because ionic compounds do not consist of molecules, and it would be technically incorrect to use the term… Read More
Monosaccharides. Both words, monosaccharide and disaccharide break down into 2 parts. The 'saccharide' bit in each means 'sugar' and comes from an ancient Greek word. The prefixes 'mono' and 'di' mean 'one' and 'two' respectively, and again they're also from ancient Greek. If you break apart a disaccharide (a two-sugars) you get a monosaccharide (a one-sugar). Both Greek and Latin are used quite a bit in biology (which stems from a time when if you… Read More
Silver halides absorb light to form elemental silver. This is the basis for the photographic film. This is an unusual reaction and is certainly not common to all ionic compounds. Silver halides are also unusually insoluble, again not a common property of ionic compounds. In fact silver halides have quite a lot of covalent character! I am sure teacher has something in mind but its certainly not in mine.
No, because the word was created in past century and there no official prefixes for "Mobile". You might found some prefixes from your friends
You use the Latin prefixes when implying a number, such as in chemistry. Example.... NO2......Nitrogen dioxide. There are two oxygen molecules, so di is used. H3O.......Hydrogen trioxide. Mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-ten. All these indicate the number of molecules in a compound. Remember, however, that you only apply prefixes in chemistry to non-metal non-metal compounds. .
For one thing, P is phosphorus, not potassium. PCl would be phosphorus monochloride. Potassium chloride, KCl, is an ionic compound where as numeric prefixes (e.g. mono-, di-, tri-) are normally used for molecular compounds.
I think that it doesn't matter because it actually depends if your confident or not used to play bass and First show I was so confident I could strip off and run around in my pants lol !!
Lewis dot structures are used to represent the covalent electrons of an element. It can be used to show the sharing of covalent electrons in a covalent bond or just to show the covalent bonds in general.
