# How to describe the the yonic value and type of bond of this formula

• transgalactic
In summary, the yonic value refers to the overall polarity of a molecule, which is determined by the distribution of electrons within the molecule. To determine the yonic value, one must identify the atoms and types of bonds present, and use electronegativity values to calculate the overall polarity. Polar molecules have an unequal distribution of electrons, while nonpolar molecules have an equal distribution. The two main types of bonds that contribute to the yonic value are polar covalent and ionic bonds, which can affect the solubility, boiling point, and reactivity of a molecule.

Br=2.8
P=2.1

i know that we should subtract them
but my formula is:
$PBr_3$

and how to know if its a yonic bond dipolar bond or covalent bond
??

Use the template please. It makes it easier to understand your question.

The yonic value of a compound refers to its electronegativity difference, which is a measure of the ability of an atom to attract electrons towards itself in a chemical bond. In this case, the electronegativity difference between bromine (Br) and phosphorus (P) is 2.8 - 2.1 = 0.7. This indicates that the bond between these two atoms is covalent in nature, meaning that the electrons are shared between them rather than being completely transferred from one atom to the other.

As for the type of bond, PBr3 is a covalent compound, which means that the bond between phosphorus and bromine is a covalent bond. This type of bond is formed when two atoms share one or more pairs of electrons, with each atom contributing an equal number of electrons to the bond. This results in a stable arrangement of electrons around both atoms, making the bond strong and difficult to break.

In conclusion, the yonic value of PBr3 is 0.7, indicating a covalent bond, and the type of bond is a covalent bond.

## 1. What is the meaning of yonic value?

The yonic value refers to the overall polarity of a molecule, which is determined by the distribution of electrons within the molecule. This can impact the molecule's reactivity and physical properties.

## 2. How do you determine the yonic value of a formula?

To determine the yonic value of a formula, you must first identify the atoms and the type of bonds present in the molecule. Then, you can use the electronegativity values of each atom to calculate the overall polarity of the molecule.

## 3. What is the difference between a polar and nonpolar molecule?

A polar molecule has an unequal distribution of electrons, resulting in a slight positive and negative charge on different ends of the molecule. Nonpolar molecules have an equal distribution of electrons and do not have a distinct positive or negative end.

## 4. What types of bonds can contribute to the yonic value of a molecule?

The two main types of bonds that can contribute to the yonic value are polar covalent bonds and ionic bonds. Polar covalent bonds occur when there is a difference in electronegativity between atoms, while ionic bonds occur when there is a complete transfer of electrons from one atom to another.

## 5. How can the yonic value of a molecule affect its properties?

The yonic value can impact the solubility, boiling point, and reactivity of a molecule. Polar molecules tend to be more soluble in polar solvents, have higher boiling points, and can participate in hydrogen bonding and other types of intermolecular forces.
