B) as it is ionic, so has strong ionic bonds between molecules, but ions cant move so charge cant move through the material, meaning it can't conduct electricity very well

A bond formed when atoms transfer elentron is a bond

lubasha [3.4K]

Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.

Indicate the direction of polarity of each of the following covalent bonds by dragging the appropriate delta notation to each en

Damm [24]

Answer:

Polarity is a property of molecules that represents the separation of electrical charges within the molecule, depending on the number and type of bonds it possesses.

The covalent bond between two atoms can be polar or apolar. This depends on the type of atoms that make it up: if the atoms are equal, the bond will be apolar (since no atom attracts electrons more strongly). But, if the atoms are different, the bond will be polarized towards the most electronegative atom, since it will be the one that attracts the electron pair with more force.

For each of the followings covalent bonds the direction of polarity is the one shown in the picture.

We see that in the C-O bond oxygen is more electronegative than carbon. Therefore, there will be a dipole vector oriented towards of the oxygen. We can represent this polarization of the bond by means of an arrow, which always points to the most electronegative atom.

Explanation:

The polarity of a chemical bond occurs when there is an asymmetric distribution of the electronic cloud of the bond around the two atoms that make up that link. This happens when both atoms have different electronegativity.

Each bond composed of different atoms generates a dipole vector, which points to the most electronegative atom.
A molecule will have as many vectors as it has covalent bonds.
If the vectors do not cancel out, then the molecule will be polar.
