Modeling Atoms, Ions, and Isotopes
1) Model and diagram a neutral Na atom and Na ion. How do the radii
compare?
2) Model and diagram an oxygen ion. What charge does it have? Explain
3) Model and diagram an Mg ion. What charge does it have? Explain
4) Model and diagram the second ionization energy at a C atom. Explain
why it is much higher than the right.
5) Model and Diagram the atom with the highest electronegitivity.
Explain why it is so high.
6) Model, diagram, and explain how an atom’s radius increases down a
group.
7) Model and diagram a neutral Cl ion. How does the radii compare?
1) Na ion has 1 less electron from Na atom.
2) It has negative charge because it gained two electrons.
3) It has a positive charge because it loss two electrons.
4) Once an atom becomes a noble gas it takes more force to remove
the electrons.
5) The 7 electrons are closer to the nucleus.
6) Electron goes to different level that is farther away.
7) Chlorine gained 1 electron, therefore it is negative.
