What 2 types of bonds that form compounds?
The two main types of chemical bonds are the ionic bondand the covalent bond. Each is discussed here on WikiAnswers, and you'll find links below to the related questions.
How do you determine if a bond is polar covalent?
Given below is the difference in electronegativity of any two elements:0.0-0.4 = nonpolar covalent bond0.4-1.7 = polar covalent bond>1.7 = ionic bondFor ex. Sodium and Chlorine (Na and Cl)Sodium's electronegativity = 0.93Chlorine's electronegativity = 3.16So, 3.16-0.93 = 2.23 which means NaCl bond is an ionic bondAnswer:When differentiating between covalent (molecular) or ionic, the type of elements in the compound decides which it is. Covalent bonds are between non-metals only. Ionic bonds are between a metal and a non-metal. Covalent bonds can either be polar or non-polar. You could determine this with the known electronegativities of the elements. First you have to represent the molecule by any means necessary (Lewis Dot Structure, lines, etc). This isn't nesessary for a compound with two atoms. Once drawn, you will know which atoms are bonded to the other atoms in the molecule. Then you look at the electronegativities for each element in one bond. If one atom's element has a higher electronegativity value than the other, then the bond is polar. If they are the same, then the bond is non-polar.The reason a bond would be polar is because one atom has a higher electronegativity value, which means that the element has more attraction to electrons than the other. If it is attracting electrons more than the other, then the electrons are spending more time one one side. The disparity of electron distribution causes one side to be slightly negative (δ-) and the other to be slightly positive (δ+).
Why it is difficult to find a completely covalent compound?
It is difficult to find a completely nonpolar covalent bond (which have no ionic character) because in this type of bond, the electrons are equally shared. This only happens when two atoms of the same electronegativity are bonded, which basically means to atoms of the same element. Thus, only elemental molecules such as diatomic chlorine gas have completely nonpolar covalent bonds.
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
Is O and F considered covalent ionic or neither?
The words "covalent" and "ionic" refer to bonds between atoms, and not atoms themselves. If you are referring to O2 and F2, the forms in which we find oxygen and fluorine, respectively, then the bond between the two oxygens is considered to be non-polar and covalent. The same can be said of the bond between the two fluorine atoms in F2. If you are referring to the bonds in the compound formed by oxygen and fluorine, you must first identify that compound. It is OF2, and is named "fluorine oxide". The bonds between the oxygen and fluorine in fluorine oxide are slightly polar and covalent. The determining property is "electronegativity", which you should look up and review. By convention, when the electronegativity difference between atoms is: < about 0.4, the bond between them is non-polar and covalent between about 0.4 - 1.7, then bond between them is polar and covalent > 1.7, then bond between them is ionic.
Where is a covalent bond found on a periodic table?
you cannot find a covalent bond on a period table dumbfak. On the periodic table you can only find elements, at their lowest level.

What elements can bond with water to create a chemical bond?
There are a number of elements that can bond with water to create a chemical bond. Some elements include hydrogen, helium oxygen and nitrogen. Why can find details of the elements on Wikipedia.
Where do you find the elements that form covalent bond?
If you have a look along the periodic table the whole left side (Groups 3-7) are non-metals (apart from Al, Ga, In, Sn, Tl, Pb, Bi) covalent bonds only form with non metals so this is where you'll find them all.
Find out what covalent bonding is?
Chemical bond in which atoms share one or more electrons.
How do you determine if a bond is polar covalent?

Is a covalent compound composed of a non-metal and a metal?
Eventhough we classify chemical bonds as ionic and covalent,when we get deeper into nature of bonds, we find that what we call an ionic bond has some amount of covalent character and vice versa.So theoritically speaking there's no such thing like nonpolar covalent bond.But if we consider cases of homonuclear diatomic molecules like O2,H2 etc. the electronegativity difference between the two bonded atoms is almost zero and hence there would be an ideal case of equal sharing of electrons by the two atoms in those molecules.Hence it may be called as a nonpolar covalent bond.

How do you know about the difference between an ionic bonding and covalent bonding?
If you are looking at a chemical bond between two elements, simply find the difference between their electronegativities (simply google a periodic table that includes electronegativity to find an element's electronegativity). So for instance, in: Pottasium + Flouride Flouride has an electronegativity of about 4.0, and Potassium has an electronegativity of about 0.8. 4.0 - 0.8 = 3.2 if the difference is from 0.0 to 0.3, the bonds are non-polar Covalent. if the difference is from 0.3 to 1.7, the bonds are polar Covalent. if the difference is from 1.7 upwards, the bonds are Ionic.
Is NaCl polar covalent?
To classify a bond as polar or covalent, you must first find the Electronegativity difference. The electronegativity of Na is 0.93 and Cl is 3.16. Therefore we find the electronegativity difference by subtracting: 3.16 - 0.93= 2.23. Therefore NaCl is an ionic bond. For electronegativity differences >1.7, the bond is ionic. For electronegativity differences between 0.4-1.7, the bond is polar covalent For electronegativity differences < 0.4, the bond is non-polar covalent.
