Question

Electronegativity of an element on Pauling scale is x its value on Muliken scale is 7. Find the value of 4x.

Answer 1

Answer:

Pauling arbitrarily chose a value of 2.1

for the electronegativity of H atom. The

EN values for other atoms were found

relative to this.

Answer 2

Given:

Electronegativity of an element on Pauling scale is x its value on Muliken scale is 7.

To find:

Value of 4x

Calculation:

General expression relating Pauling scale and Mulliken scale of Electronegativity.

$\boxed{ \sf{X_{pauling} = 0.336 \bigg \{X_{mulliken} - 0.615 \bigg \}}}$

$\sf{ = > x = 0.336 \bigg \{7 - 0.615 \bigg \}}$

$\sf{ = > x = 2.145}$

Value of 4x :

$\sf{ = > 4x =4 \times 2.145}$

$\sf{ = > 4x =8.58}$

So, final answer is:

$\boxed{ \sf{ value \: of \: 4x =8.58}}$

Related information:

• Pauling and Mulliken scales are two different scales measuring the electronegativity of atoms of various elements.

• The electronegativity of any element denotes its tendency to pull electrons towards itself.

• Electronegativity is very much different from electron gain enthalpy which denotes the heat released after accepting an electron.
