Read This!The attractive and repulsive forces in an atom are rather complex. An electron is attracted to the protonsin the nucleus, but it is also repelled by the other electrons in the atom. It is important to note howeverthat the attractive force of the nucleus is NOT divided up among the electrons in the atom. Each electrongets approximately the full attractive force of the nucleus (minus the repulsive effects of other electrons).Compare the diagram below to set D in Model 3. Notice the similarity in attractive force.0.10 nm0.10 nmapprox. 4.60 x 10*(on cach electron)Model 4 – Period 3 ElementsSodiumAluminumChlorineWhat do you SEE?What does it MEAN?What do you WONDER?Does the distance between the valence electron(s) and the nucleus change as you move from leftto right?Can the differences in the attractive forces shown by the arrows be explained by a change in thedistance between the electrons(s) and the nucleus?3.Can the differences in attractive forces shown by the arrows be explained by a change in thenumber of protons in the nucleus? Explain.arch2.

Yes, the distance between valance electron(s) and the nucleus (atomic radius) changes as we move…
