Slide 1 - Tekstslide

Slide 2 - Tekstslide

Slide 3 - Tekstslide

Slide 4 - Tekstslide

  •  State that:
  • (a) Group VIII noble gases have a full outer shell
  • (b) the number of outer shell electrons is equal to the group number in Groups I to VII
  • (c) the number of occupied electron shells is equal to the period number
  • Define isotopes as different atoms of the same element that have the same number of protons but different numbers of neutrons
My Goals Today:

Slide 5 - Tekstslide

  • Interpret and use symbols for atoms, e.g. 162C, and ions, e.g. 3517Cl 
  • State that isotopes of the same element have the same chemical properties because they have the same number of electrons and therefore the same electronic configuration
My Goals Today:

Slide 6 - Tekstslide


Slide 7 - Tekstslide

Atom (Neutral: 0)
  • when P = E

Ion (Charged: +/-)
  • when P is NOT EQUAL to E
Atom vs. Ion
