1. Metal atoms lose electrons. 2. Nonmetal atoms can gain electrons. 3. An atom that has gained or lost an electron is an ion. 4. An ionic bond forms between positively and negatively charged ions.
Ionic Bonds—Electron Transferring 5. When forming a compound, the nonmetal atoms gain the electrons that was lost by the metal atoms. 6. The attraction between positively and negatively charged ions in an ionic compound is an ionic bond.
Formation of Cations 7. Metals give away electrons to attain a noble gas configuration. 8. Lose electrons =positive ions (cationsmeow, pawsitive!) 9. Draw a Neon atom
10. 11. 11+
Electron Dots For Cations 13. A charge of +1 means the loss of an electron while a charge of -3 means an atom gained 3 electrons and is now an ion. 14. Write the electron dot model for calcium.
Electron Dots For Cations Did you draw this? Do metals lose or gain electrons? Ca
Electron Dots For Cations Ca 2+ Ca 14. The first box was a calcium atom what is the second box?
Formation of Anions 15. Nonmetals gain electrons to look like a noble gas configuration. 16. They “get a minus” or gain electrons so they are negative ions. 17. Draw an Oxygen atom.
Electron Dots For Anions 18. The first box was an oxygen atom what is the second box?
19. With metals the valence electrons are free to move around are called a sea of electrons. This is called a metallic bond-since the aluminum nuclei share the electrons.
