The large difference in electronegativity between the elements in the compound is the best indicator that a compound may be ionic. Ionic compounds typically form between elements with a large electronegativity difference, resulting in the transfer of electrons from one element to another.
What else can I help you with?
What ionic compound is Ca Br?
The ionic compound calcium bromide is CaBr2.
Which liquid solvents are best for dissolving ionic compounds and why?
Polar solvents such as water, alcohols, and acetone are best for dissolving ionic compounds because they have the ability to break apart the strong ionic bonds in the compound due to their positive and negative charges. This allows the individual ions to be surrounded and solvated by the solvent molecules, leading to the dissolution of the ionic compound.
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!
What is the best example of a true ionic compound?
Sodium chloride (NaCl), commonly known as table salt, is a classic example of a true ionic compound. It is formed by the transfer of electrons from sodium (Na) to chlorine (Cl), creating ions with opposite charges that are held together by electrostatic forces.
Is ferrous oxide a covalent or ionic?
Ferrous oxide (FeO) is considered an ionic compound because it is formed by the transfer of electrons between iron (Fe) and oxygen (O) atoms. Iron loses electrons to oxygen, creating Fe2+ cations and O2- anions that are held together by ionic bonds.
What ionic compound is Ca Br?
The ionic compound calcium bromide is CaBr2.
Which property is the best to use when determining the strength of an ionic bond in a solid?
lattice energy

What is the formula for ionic compound formed between B and O?
Boron triuoxide, B2O3. (If teacher says its ionic then that's OK) B2O3 is more covalent than ionic the electronegativity difference is only 1.4 and boron is not a metal. It is best described as a giant covalent molecule.
Is AgNO3 covalent or ionic?
Disilver oxide, Ag2O silver(I) oxide is ionic using the simple rule of thumb "metal plus non metal" gives an ionic compound. But looking more deeply it is probabaly best described as covalent. Checking the electronegativities, Ag (1.93) O (3.44) the difference is only 1.5- which is borderline for ionic and covalent. Looking at the crystal structure, Ag2O as the same structure as Cu2O. Each silver atom has 4 near neighbour oxygen atoms and each oxygen has two near neighbour silver atoms. This very different from the more typical "antifluorite structures" of the more obviously ionic alkali metals where the metal atoms have 4 oxygen near neighbours and the oxygen atoms 8 metal atom near neighbours. Additionally in Ag2O three atoms are in a line O Ag O indicating sp hybridisation.
Table salt sodium chloride one of the most common substances occurring in nature is best classified as what compound mixture solution alloy amalgam?
Sodium chloride (NaCl) its a compound, an ionic salt.
Is ferrous oxide a covalent or ionic?
Ferrous oxide (FeO) is considered an ionic compound because it is formed by the transfer of electrons between iron (Fe) and oxygen (O) atoms. Iron loses electrons to oxygen, creating Fe2+ cations and O2- anions that are held together by ionic bonds.
Which liquid solvents is best for dissolving ionic compounds?
Polar solvents such as water, methanol, ethanol, and acetone are commonly used to dissolve ionic compounds. These solvents have a high dielectric constant, which helps in overcoming the strong electrostatic forces between ions in the ionic compound, allowing them to dissociate and dissolve.
Is AlP an ionic or molecular compound?
AlP is a solid and it is not molecular. The difference in electronegativity is only 0.58. The bonding is It is best described as polar covalent . There are many compounds that are not molecular but are covalent giant molecules.
Is FeCl3 an ionic compound?
Solid FeCl3 (ferric chloride or Fe(III) chloride) is indeed ionic. there are two forms the anhydrous and hexahydrate FeCl3.6H2O. In the vapour phase it forms a dimer Fe2Cl6 which has the same chlorine bridged structure, Al2Cl6 ,as aluminium trichloride does in the vapour phase. The bonding in this well its probably best described as polar covalent.
