One method for calculating `Z_(eff)` is to use the equation:
`Z_(eff) = sqrt(((E)(n^(2)))/(1312kJ//"mole"))`
where E is the energy necessary to remove an electron from an atom and n is the principal quantum number of the electron. Use this equation to calculare `Z_(eff)` value for the highest energetic electron in potassium. `E = 418.8 kJ//"mole"`

A

`2.86`

B

`2.26`

C

`3.26`

D

`2.00`

Text Solution

Verified by Experts

The correct Answer is:
B
`Z_(eff) = sqrt((418.8)/(1312)xx4^(2)) = 2.26`
