How can you tell the difference between ionic and covalent bond only by looking at the chemical formula?
A compound formed by ionic bond will have charges written on the Chemical formula of the compound since ionic compounds carry charges. But, covalent compounds won't have charges associated with them because they are not formed by the transfer of electrons. Another way of telling the difference is by looking at the valencies. One of the elements present in a covalent compound will have tetra-valency i.e., a valency of 4.
Is CaSO4 Ionic or covalent?
You cannot tell from a formula whether an compound is ionic or molecular. The distinction is arbitrary at best, and there are actually very few purely ionic compounds. Al2S3 will be somewhere between ionic and covalent. Depending what level you are at and wherer you are taught different classifications of aluminium sulfide are given. See link for one view. Al2S3 is a colorless high melting compound, the aluminium atoms are in tetrahedral coordination in the most stable forms. This is line with the size difference between S and Al. The electronegativity difference between Al and S is ony 0.97. These are factors that need to be taken into account when making a decision. My view is partially covalent partially ionic!
If you look at a compound how can you tell if its a covalent or an ionic bond?
You would need to know the chemical makeup of the compound. Ionic bonding occurs between a metal and a non-metal while covalent bonding occurs between non-metals
How do you tell if a bond is covalent?
if it occurs between non metal atoms. Covalent bonds can only occur between non metal atoms but Ionic bonds occur between metal and non metal atoms.
How to tell if a bond is ionic or covalent?
if you have a metal and non metal bonding it's an ionic bond and if it's two non metals it would be a covalent bond.
Why is ionc compounds stronger than covalent compounds?
By stronger, I am guessing you meant " stronger intermolecular forces ". Ionic compounds do not necessarily have stronger intermolecular forces than covalent compounds. For example, it is true that NaCl(an ionic compound) has strong electrostatic attractions while H2O(a covalent compound) has very weak London forces. However, SiO2 is a giant covalent compound, and has very strong covalent bonds between molecules, even stronger than the electrostatic forces of NaCl.

Why is the electronegativity difference of 1.7 important as a line on a graph?
It's so you can easily tell the difference between Covalent Bonds and Ionic Bonds by looking at the graph. Above the 1.7 line is Ionic Bonds and below the 1.7 mark is Covalent Bonds.
Is Nitrogen trichloride covalent?
NO2 is covalent. Usually you can tell when a compound is ionic or covalent by the elements it is composed of. A nonmetal and a nonmetal with be covalent, while a metal and a nonmetal will be ionic.
What do the numerical prefixed used in naming covalent compounds tell you?
nothing
Ionic bonding vs covalent bonding?
An Ionic bond is one where an element gives away electrons to another, forming Ions. It usually occurs between metals and nonmetals. Another way to tell is if the electronegativity difference between the elements is greater than 2.0 then it is an ionic bond. A covalent bond is one where the elements share electrons with one another. It usually occurs between nonmetals. If the electronegativity difference between the elements is 2.0 or less it is a covalent bond.
What will you look for to know if a compound is ionic or covalent?
An ionic compound is when the an atom gives away or receives electrons to become stable. A covalent compound is when the atoms share electrons to become stable.It is a Ionic bond because it is between nonmetals and metal
What is the example of the uses of covalent compounds as solvent in our daily life?
A covalent compound is a compound in which the atoms that are bonded share electrons rather than transfer electrons from one to the other. While ionic compounds are usually formed when metals bond to nonmetals, covalent compounds are formed when two nonmetals bond to each other. Covalent compounds have the following properties (keep in mind that these are only general properties, and that there are always exceptions to every rule): 1) Covalent compounds generally have much lower melting and boiling points than ionic compounds. As you may recall, ionic compounds have very high melting and boiling points because it takes a lot of energy for all of the + and - charges which make up the crystal to get pulled apart from each other. Essentially, when we have an ionic compound, we need to break all of the ionic bonds in order to make it melt. On the other hand, when we have covalent compounds we don't need to break any bonds at all. This is because covalent compounds form distinct molecules, in which the atoms are bound tightly to one another. Unlike in ionic compounds, these molecules don't interact with each other much (except through relatively weak forces called "intermolecular forces"), making them very easy to pull apart from each other. Since they're easy to separate, covalent compounds have low melting and boiling points. 2) Covalent compounds are soft and squishy (compared to ionic compounds, anyway). The reason for this is similar to the reason that covalent compounds have low melting and boiling points. When you hit an ionic compound with something, it feels very hard. The reason for this is that all of the ionic bonds which hold together the crystal tend to make it very inflexible and hard to move. On the other hand, covalent compounds have these molecules which can very easily move around each other, because there are no bonds between them. As a result, covalent compounds are frequently flexible rather than hard. Think of it like this: Ionic compounds are like giant Lego sculptures. If you hit a Lego sculpture with your fist, it feels hard because all of the Legos are stuck very tightly to one another. Covalent compounds are more like those plastic ball pits they have at fast food playgrounds for little kids. While the balls themselves are held together very tightly (just like covalent molecules are held together tightly), the balls aren't really stuck to each other at all. As a result, when little kids jump into the ball pits they sink in rather than bouncing off. 3) Covalent compounds tend to be more flammable than ionic compounds. The main reason that things burn is because they contain carbon and hydrogen atoms that can react to form carbon dioxide and water when heated with oxygen gas (that's the definition of a combustion reaction). Since carbon and hydrogen have very similar electronegativities, they are mostly found together in covalent compounds. As a result, more covalent compounds than ionic compounds are flammable. There are a couple of exceptions to this rule. The first is with covalent compounds that contain neither carbon nor hydrogen. These tend not to burn, and if they do, they burn by mechanisms other than the classic combustion reaction. The other exception comes with ionic compounds referred to as "organic salts". These organic salts are ionic compounds in which the anion is basically a big covalent molecule containing carbon and hydrogen with just a very small ionic section. As a result, they burn even though they're technically ionic compounds. 4) Covalent compounds don't conduct electricity in water. Electricity is conducted in water from the movement of ions from one place to the other. These ions are the charge carriers which allow water to conduct electricity. Since there are no ions in a covalent compound, they don't conduct electricity in water. 5) Covalent compounds are insoluble in water. Naming Covalent Compounds Covalent compounds are much easier to name than ionic compounds. Here's how you do it: All covalent compounds have two word names. The first word typically corresponds to the first element in the formula and the second corresponds to the second element in the formula except that "-ide" is substituted for the end. As a result, HF is named "hydrogen fluoride", because hydrogen is the first element and fluorine is the second element. If there is more than one atom of an element in a molecule, we need to add prefixes to these words to tell us how many are present. Here are the prefixes you'll need to remember:<center>Number of atoms Prefix </center>1 mono- (use only for oxygen) 2 di- 3 tri- 4 tetra- 5 penta- 6 hexa- 7 hepta- 8 octa- Let's see how this works: Examples: P2O5 - this is named diphosphorus pentoxide, because there are two phosphorus atoms and five oxygen atoms. CO - this is carbon monoxide (you need the "mono-" because there's only one oxygen atom). CF4 - this is carbon tetrafluoride, because there's one carbon atom and four fluorine atoms.
