It depends what authority you use, generally greater than 1.7- 2. Make sure you use the one your teacher and examiners are expecting otherwise your predictions will not appear to be correct.

Classify GAAs as whether metallic ionic or covalent?
covalent
Does magnesium nitride have a ionic or covalent bond?
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic. A table of ELECTRONEGATIVITY can help one determine whether a bond is ionic or covalent. The bigger the difference in electronegativity the more ionic the bond.
How do you distinguish between an ionic and a covalent compound?
As a general rule, the further apart elements are on the periodic table, the more likely the compound that they form is ionic. Consequentlly, the closer they are, the more likely they will be covalent. If you have the electronegativity values for the elements in question, you can calculate whether the compound is covalent, polar covalent, or ionic. Find the absolute valule of the difference between the electronegativities of the elements. If the difference is: 0 to .5 = covalent .5 to 1.9 = polar covalent 1.9 to infinity = ionic
What is the formula for carbon difluoride covalent?
CF2, based on the name. Whether this compound actually exists is dubious.
How do you know whether a bond between two atoms is ionic or covalent?
* If one atom is metal and the other is non-metal, the bond is ionic * If both atoms are non-metal, the bond will be covalent.
How do you determine whether a compound with more than two elements such as Al2(SO4)3 is ionic or covalent?
When the difference between the electronegativities of two elements is in the range 0-2 (Pauling system) the bond is covalent; generally compounds between nonmetals are covalent.
Classify GAAs as whether metallic ionic or covalent?
covalent
How can an estimated sum or difference be useful?
it can help you determine whether toy made an error in calculating an exact sum or difference.

Statistics are not used by scientists to do what?
Data Scientists can help determine whether or not that difference is significant enough to warrant increased attention.
How can you determine whether the arithmetic sequence has a positive common difference or a negative common difference?
If the terms get bigger as you go along, the common difference is positive. If they get smaller, the common difference is negative and if they stay the same then the common difference is 0.
Why does chemical formula help identify whether a substance is ionic or covalent?
Generally compounds formed between nonmetals are covalent.
How do you determine whether a rock is a rhyolite or an andesite?
The composition of the rock will determine whether it is a rhyolite or an andesite.
What are the bonds called which hold atoms together?
The nature of the bond will vary on the element under consideration and the difference in electronegativities between the two atoms. Atoms can form ionic bond, covalent bond, coordinate-covalent bond or hydrogen bond.

How do you know if the the chemical formula helps in identifying whether a substance is ionic or covalent?
Generally compounds formed between nonmetals are covalent.
Does the bouyant force on a submerged object depend on the weight of the object?
No, but the difference between the buoyant force and the weight of the object will determine whether it floats or sinks.
