What does it mean when a covalent bond is polar and how can you tell?

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!!

∙ 14y agoA covalent bond is formed by sharing of one or more electron pair between two atoms when each atom contributes electrons equally. Atoms can be of same or different elements (electronegativity difference should be small i.e. <2.0).
If the atoms are of same element then the shared electrons are equally distributed between them and the bond is non-polar.
But if atoms are of different elements then the atom having higher value of electronegativity (tendency of an atom to attract electrons in a chemical bond) attracts the shared pair of electrons more strongly, due to this the electron pair is more shifted towards this atom. The less electronegative atom gets a fractional positive charge and more electronegative atom gets a fractional negative charge. Such bonds in which one end appears positive and other negative (i.e. bond has two oppositely charged poles) is called a polar covalent bond.

How can you tell what type of bond atoms have with each other?
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.
Is Nitrogen trichloride covalent?
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.
How to tell if a bond is ionic or covalent?
if you have a metal and non metal bonding it's an ionic bond and if it's two non metals it would be a covalent bond.
What list of items water will dissolve other than salt sugar?
Anything that is bonded by an ionic or polar-covalent bond.
How do you know when a bond is ionic or covalent?
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).
What describes bonding in a polar covalent bond?
i dont know. you tell me
How can you tell if an atom has a covalent bold?
If it is a non-metal to non-metal bond than it is covalent. For example, CO2 is a covalent bond.

How can you tell if a bond bond is polar or non-polar?
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.
Is Brl a polar nonpolar ionic or not enough information to tell?
IBr iodine monbromide is covalent- and the electronegativity difference is small- so nonpolar
How can you tell a covalent molecule?
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.
Why tetra covalent bond not exist?
Can't tell you, because they really DO exist: in methane (CH4) and other alkanes all C atoms have four covalent bonds with H and/or other C atoms.
Ionic bonding vs covalent bonding?
An Ionic bond is one where an element gives away electrons to another, forming Ions. It usually occurs between metals and nonmetals. Another way to tell is if the electronegativity difference between the elements is greater than 2.0 then it is an ionic bond. A covalent bond is one where the elements share electrons with one another. It usually occurs between nonmetals. If the electronegativity difference between the elements is 2.0 or less it is a covalent bond.
