Tell me what you know about the different trends, reactivity etc??
Reactivity Increases, Atomic Radius Increases, Ionization energy= decreases Melting Point = Decreases, metallic ions bigger but same electrons, blip at Mg (crystal structure changes)
1 of 5
Reactions with water?
Metal hydroxide + halogen is oxidisedHydrogen formed,reaction rate increases down group
2 of 5
What are Barium Meals?
Barium sulfate opaque, coats tissues, can be seen with xray
3 of 5
Tell me about the solubility down the group of compounds?
with OH = solubility increase S04 = Decreases (barium sulfate insoluble)
4 of 5
Test for sulfate ions?
Acified barium chloride ( this because to remove sulfites + carbonates) + solution with sulfate ions (white barium sulfate formed)
