As the number of protons in an atom increases, the positive charge of the nucleus becomes stronger. This increased positive charge enhances the attractive force that the nucleus exerts on the surrounding electrons. As a result, electrons are held more tightly to the nucleus, which leads to a number of observable effects on atomic properties.

One significant effect of having more protons is the increase in effective nuclear charge, which is the net positive charge experienced by electrons. This greater attraction not only helps in stabilizing the electron cloud around the nucleus but also affects other properties such as electronegativity. Atoms with more protons typically have higher electronegativity values because they can attract and hold onto electrons more effectively compared to atoms with fewer protons.

The option mentions that the number of protons enhances the nucleus's ability to hold onto its electrons, which is directly tied to the concept of effective nuclear charge. Consequently, as you move across a period in the periodic table, the increasing number of protons leads to a general trend of stronger binding of electrons, influencing the chemical and physical characteristics of the elements.

In summary, the correct choice accurately describes how an increase in the number of protons influences atomic properties by enhancing the nucleus's ability to attract and retain
