The electrical force between an inner electron and the nucleusof an atom is: . larger for atoms of low atomic numberb. largerfor atoms of high atomic numberc. the same for all atoms

b. Larger for atoms of high atomic number.

Explanation:

The atomic number  of a chemical element is the number of protons found in the nucleus of every atom of that element.

The electrical force between an inner electron and the nucleus of an atom is described by  the Coulomb law

           where k: Coulomb constant

                       q1 and q2 are the electric charges that interact (in our case  electron and protons)

                       r: Distance between electron and each proton

Then, larger number of protons in the nucleus, more the electrical force will be.

The answer is:

b. Larger for atoms of high atomic number.

i think the answer is a, hope this is right, that would be my best guess.
