slide1

See me for a number.Get with the person that has the same number.You and your partner will make 3 color group (20 pieces each)Find your work table with the same number.

slide3

On your paper atomic model handout, identify the color to represent protons, neutrons and electrons.

  • On your paper atomic model build helium.
    • Draw in notebook as well.
slide4

Discuss and write in your notebook what would this atoms be if you changed…

    • The number of protons?
    • The number of electrons?
    • The number of neutrons?
slide5

Build hydrogen then…

    • Change the number of protons?
    • Change the number of electrons?
    • Change the number of neutrons?
slide7

Discuss, build and draw in your notebook C, N, O and F.

  • Discuss how the number of electrons on the outer orbital of C, N, O and F relates to how stable the element is?
slide8

Discuss and write in your notebook electronegativity. Note the trends of electronegativity as you move across the periodic table left to right and then top to bottom.

slide9

Discuss and write in your notebook which elements are the most stable?

  • Discuss and write in your notebook which elements are the most reactive?
slide11

Discuss the stability of the fluorine and hydrogen model you just built.

  • Show how the loss/gain of an electron will stabilize the atoms’ outer orbital.
  • Discuss how and why these atoms have formed an ionic bond.
  • Draw a before and after diagram of HF molecule in your notes.
  • Now build LiCl, MgO, and BeS. Be sure to draw before and after diagrams of each in your note.
slide12

build LiCl, MgO, and BeS. Be sure to draw before and after diagrams of each in your note.

  • For each of the above, identify the cation and anion
discuss and write
Discuss and write…
  • Which elements of the periodic table tend to become negative ions. Why?
  • Which elements of the periodic table tend to be positive ions. Why?
  • Which columns would combine well in order for both to be more stable.
  • Why don’t all the elements of the periodic table from ionic bonds?
  • What do atoms that cannot form ionic bonds do to become more stable
