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.
If a compound is made from a metal and a non-metal, its bonding will be ionic.If a compound is made from two non-metals, its bonding will be covalent. Compounds containing two elements (so called binary compounds) can either have ionic or covalent bonding.
Binary covalent compounds consist of two nonmetals that share electrons to form a covalent bond. They have simple molecular structures with low melting and boiling points. They do not conduct electricity in any state.
You can determine the type of bond in a compound by analyzing the difference in electronegativity between the atoms involved. If the electronegativity difference is small (less than 1.7), it's a polar covalent bond. If the difference is large (greater than 1.7), it's an ionic bond. If the difference is zero, it's a nonpolar covalent bond.
it is the stupidest compound whos valency is really difficult to find
i asked you the same question and you are asking me to answer it. oh man so i got no way to find the answer to this question
find out yourself and stop depending on people

it is something that one find it hard to completely understand

The formula unit of a compound represents the simplest whole number ratio of elements in the compound. This can be determined by looking at the molecular formula of the compound or by performing chemical analysis to find the empirical formula. The formula unit is used in ionic compounds, while the molecular formula is used for covalent compounds.
No. Aspirin is composed of acetylsalicylic acid and inert filler (such as starch). Benzodiazepine is a completely different 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
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.
