Answer:
A. Electron distribution
Explanation:
Electron distribution is a function which gives the number of electrons per unit volume of phase space.
To calculate an electron configuration (or distribution), divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
Hope this helps!
