It's a bond in which a pair of electrons is shared between two atoms, but being held more closely by one of the atoms. apex :]
ignore this:
when a covalent bond is polar, it mostly means that when you see a graphed picture of it. notice that it is slightly bent!!
You could determine the type of bond present in an unknown sample by observing waters effect on it. If it dissolved it suggest covalent bonds. If it remains solid suggest the substance is ionic.
NO2 is covalent. Usually you can tell when a compound is ionic or covalent by the elements it is composed of. A nonmetal and a nonmetal with be covalent, while a metal and a nonmetal will be ionic.
One way to determine if a bond is ionic or covalent is to look at the electronegativity difference between the two atoms. If the difference is large (greater than 1.7), the bond is likely ionic. If the difference is small (less than 1.7), the bond is likely covalent. Additionally, ionic bonds typically form between a metal and a nonmetal, while covalent bonds form between two nonmetals.
An ionic bond is one in which electrons are gained/lost, ions are formed, and they attract, forming an ionic compound (e.g., HCl, H2SO4,Li2O) A covalent bond is one in which electrons are shared, and depending on the size of the atoms involved, could be polar (H2O) or nonpolar (N2).
A molecular compound is considered polar if the individual bond dipoles do not cancel each other out due to molecular symmetry. One way to determine if a compound is polar is to look at the electronegativity difference between the atoms in the bond: if there is a significant difference, the bond is likely polar. Additionally, the molecular shape and symmetry can also influence polarity.
i dont know. you tell me
If it is a non-metal to non-metal bond than it is covalent. For example, CO2 is a covalent bond.

Check the electronegativities of the atoms in the bond. The bond will be polar if there is a difference in electronegativity. The most electronegative element will attract the bonding eletrons to it becoming slightly negatively charged. The other end of the bond will become slightly positively charged. For example a bond between carbon and chlorine, C-Cl: C electronegativity 2.55 Cl electronegativity 3.16 The bond will be polar because of the difference in electronegativity, and Cl will be slightly negative, carbon slightly positive.

When a covalent bond occurs between elements, there is only involved nonmetals and metalloids. Covalent molecules will only contain nonmetals and metalloids. Covalent bonds are also formed by multiple atoms sharing electrons, so the substance will have a relatively low melting point.
Tetra-covalent bonds do not exist because carbon typically forms four covalent bonds by sharing electrons with other atoms. In a tetra-covalent bond scenario, it would have to share four electrons with another atom, which is energetically unfavorable and generally not observed in nature.
Vinegar is made of all nonmetals. Covalent bonds are all nonmetals, ionic is a metal and non metal, and there are metallic bonds. You can also tell because of the electronegativity. It is between 0.0 and 1.67
the group in which an element falls = # of valence electrons eg Na gp 1 = 1 valence e Ca, gp 2 = 2 valence e and so on....... the number of covalent bond an element makes really depends on which other element it bonds with but note this a covalent bond consist of 2 electrons so how many covalent bonds formed will depend on how many electrons an atom has in its valence shell - covalent bond are mostly between non metals and involves electron sharing carbon forms the longest chain of covalent bonds with itself...
