6. Ionic bonds form when oppositely charged simple ions are attracted to one another. 7. To satisfy the octet rule, metals will become positively charged and nonmetals will become negatively charged during ionic bond formation. 8. What elements will gain or lose electrons when ionic bond is formed?- Be Beryllium (2electrons), and Al Aluminum(3electrons) will lose electrons. O Oxygen will gain(2electrons)and I Iodine will gain(1 electron) 9.Changes that atoms will undergo to obtain noble gas configuration: A. Se- Se+2e- -- >Se2- B. Ba-Ba2+2e- C. Element 10- Neon gabs is a noble gas, no change D. Nitrogen- N+3e -- > N3- 10. More changes to obtain noble gas configuration: a. K- K+ 1e- b. Mg-Mg+2e- c. Al- Al3+ +3e- d. P- P+3e-”P3- e. S- S+2e- “S2- f. Cl- Cl+1e”Cl- G. Ar- already has noble gas configuration 11. The term isoelectronic is when an atom or ion have the exact same electric configuration. 12. Ionic compounds are formed as metals and nonets react with one another, meats lose electrons and non-metals gain electrons. 13. Attached in photo 14. Attached in photo 15. Attached in photo 16.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
