What is it about the elements in a column of the Periodic Table that makes them behave similarly? Select one:
a. Electron distribution
b. Neutron number
c. Atomic number
d. Atomic mass

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!

A. Electron distribution

is the correct answer…...
