If the difference in electronegativity between the elements is greater than 2 then the bond will be ionic, if its between 1.6 and 2 then it will be ionic if one of the elements is a metal.

What is the simplest rule being used in determining whether the bond between two atoms is ionic or covalent?
Simplest rule: metal + non-metal gives an ionic bond Next simplest: electronegativity difference greater than say 1.7 Remember rule 1 "In inorganic chemistry there are exceptions to every rule even this one"
What rule of thumb is useful for predicting whether one substance will dissolve in another?
The rule of thumb that is useful for predicting whether one substance will dissolve in another is "likes dissolves likes". Similarity of substances depends on the type of bonds, intermolecular forces between solute and solvent, and if it is non-polar or polar molecule.
Is Mgcl an ionic compound?
Yes, MgCl is an ionic compound. It is an ionic compound because the bond between these two elements is an ionic bond. So, what is an ionic bond? An ionic bond is a bond between elements that form cations (positive ions) and anions (negative ions). The rule is thumb is that metals usually form ionic bond with non-metals. This happens since non-metals really want to gain electrons while metals really want to lose electrons, and so they would become anion and cation, respectively. Anions and cations are attracted to each other which create an ionic bond. Mg is a metal and Cl is nonmetal; thus, MgCl is an ionic compound.
How does the rule of zero charge help ypu predict the formula of an ionic?
The rule of zero helps you predict the formula of an ionic compound because the anion will always want to bond with a action to get zero net charge on the compound.
What is the type of bond that is present between sodium and fluorine in sodium fluorine which is used in fluoridation of drinking water?
The bond between sodium and fluorine in sodium fluoride is an ionic bond. In an ionic bond, one atom donates an electron to another atom, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces. Sodium fluoride is commonly used in fluoridating drinking water to improve dental health.
Is mg2 ionic or covalent?
Ionic, When trying to figure out the type of bond just use this simple rule. If the atoms are two nonmetals then the bond is covalent. If one of the atoms is nonmetal and the other is a metal then the bond will be ionic. This is due to differences in electronegativity.
How can you figure out if a bond is ionic or covalent?
The difference in electronegativity between the atoms that are bonded. A difference of more than about 1.7 indicates that the bond will be ionic. Health warning - this is only a rule of thumb.
What is Fajan's rule?
Fajans' Rules, formulated by Kazimierz Fajans in 1923, are used to predict whether a chemical bond will be covalentor ionic, and depend on the charge on the cation and the relative sizes of the cation and anion.IonicCovalentLow positive chargeHigh positive chargeLarge cationSmall cationSmall anionLarge anionThus sodium chloride (with a low positive charge (+1), a fairly large cation (~1 Å) and relatively small anion (2Å) is ionic; but aluminum iodide (AlI3) (with a high positive charge (+3) and a large anion) is covalent.
If two atoms of nitrogen were to join together to form a bond between themselves and obey the octet rule would their bond be likely to be ionic or covalent?
The bond formed between two nitrogen atoms would most likely be a covalent bond. This is because nitrogen atoms are nonmetals and tend to share electrons to achieve a stable octet configuration, rather than transferring electrons to form an ionic bond.
What kind of bond is presented in HCI?
A covalent bond is presented in HCl, which is formed when hydrogen and chlorine atoms share electrons to meet the octet rule. This results in a stable molecule with a polar covalent bond due to the difference in electronegativity between hydrogen and chlorine.
How can eletronegativity be used to distinguish between an ionic bond and a covalent bond?
If electronegativity varies by more than 1.4 then you are most probably looking at an ionic bond. A variance less than 1.4 means, usually a covalent bond can be formed. This is a rule of thumb and is not always reliable. Metal to nonmetal; ionic. nonmetal to nonmetal; covalent.
What is the electronegativiities difference that usually is the dividing line between covalent and ionic bonds?
Typically, an electronegativity difference greater than 1.7 is considered the dividing line between ionic and covalent bonds. If the difference is equal to or greater than 1.7, the bond is considered ionic, while if it is less than 1.7, the bond is considered covalent.
