Question

Calculate %ic of the interatomic bonds for the intermetallic compound al6mn. on the basis of this result, what type of interatomic bond would you expect to be found in this compound?

Answer 1

Without specific electronegativity values, the exact percentage of ionic character (%ic) of Al6Mn cannot be determined. However, given that Al6Mn is an intermetallic compound, it is expected to display metallic bonding, due to the nature of metals and their characteristic 'sea' of delocalized electrons.

Step-by-step explanation:

To calculate the percentage of ionic character (%ic) for the intermetallic compound Al6Mn, one must consider the difference in electronegativity between the aluminum (Al) and manganese (Mn) atoms. This calculation typically involves the use of formulas derived from experimental data, such as the Pauling scale, and the data is not provided in the question. Without the specific electronegativity values or a clear formula to apply, we cannot compute the exact %ic. However, we can analyze the type of bonds expected in Al6Mn based on general principles of metallic bonding.

Al6Mn, being an intermetallic compound, would exhibit metallic bonding characteristics. This type of bonding involves a lattice of metal cations surrounded by a 'sea' of delocalized electrons. These electrons are free to move throughout the structure, which allows metals to conduct electricity and heat efficiently. Considering the presence of Al and Mn, both being metallic elements, it is logical to expect metallic bonds in Al6Mn. Additionally, the high electrical and thermal conductivity commonly associated with metals further supports this bond classification.

Answer 2

Answer : % ionic character is 0.20%

Bonding between the two metals will be purely metallic.

Step-by-step explanation: For the calculation of % ionic character, we use the formula

`\% \text{ ionic character}= [1-e^{(-(X_A-X_B)^2))/(4)}]*(100\%)`

where
`X_A` &
`X_B` are the Pauling's electronegativities.

The table attached has the values of electronegativities, by taking the values of Al and Mn from there,

`X_(Al)=1.61`

`X_(Mn)=1.55`

Putting the values in the electronegativity formula, we get

`\% \text{ ionic character}= [1-e^{(-(1.61-1.55)^2))/(4)}]*(100\%)`

= 0.20%

Now, there are 3 types of inter atomic bonding

1) Ionic Bonding: It refers to the chemical bond in which there is complete transfer of valence electrons between atoms

2) Covalent Bonding: It refers to the chemical bond involving the sharing of electron pairs between 2 atoms.

3) Metallic Bonding: It refers to the chemical bond in which there is an electrostatic force between the positively charged metal ions and delocalised electrons.

In
`Al_6Mn` compound, the % ionic character is minimal that is
`\sim`0.20% and there are two metal ions present, therefore this compound will have metallic bonding.
