The increase in atomic number causesf an increase in the strong positive charge of the nucleus.  Thus, the positive charge increases due to the number of positive protons increasing in the nucleus. The strong positive charge of the nucleus has a strong pull on the negatively charged electron...

Yes the question might need to be rephrased.  You have to be familiar with Rutherford's and Bohr's model. Rutherford discovered, based on the gold foil experiment, that the atom consists of a dense positive nucleus with negative electrons traveling around it.  His model was known as...
