Editor's Notes
- How is it organized? By atomic number What are groups? Vertical rows What are periods? Horizontal rows What are families? That’s what this PowerPoint will cover
- Group 1A called Alkalai Metals Found on the very left side of table Li, Na, K, Rb, Cs, Fr Very reactive metals, soft enough to be cut with a knife
- Group 2A Alkaline Earth Metals Found on the left side of the table next to the alkalai metals Be, Mg, Ca, Sr, Ba, Ra Not as reactive as Alkalai metals in group 1A
- Found in the middle of the periodic table Play important role in living organisms Metals that are valuable as strong, structural materials
- Also called Inner Transition metals Lanthanides: soft, silvery metals and less reactive than alkaline earth metals Actinides: all radioactive Explain why they are found at the bottom of the table.
- Also called semi-metals Have some properties of metals and some properties of non-metals
- Group 7A called halogens Fl, Cl, Br, I, At Very reactive due to strong attraction to electron Halogen means salt former
- Group 8A Noble gases Located at the far right of the table He, Ne, Ar, Kr, Xe, Rn Least reactive
