Document Summary
The 10 things you need to know for dr. larsen"s class . 2mh: reactions with o: forms oxide ion (o2-), peroxide ion (o2. 2-), or superoxide ion (o2: oxides, 2li + o2. Ko2: k + o2, cs + o2 cso2, rb + o2 rbo2, reactions with h2o: the alkali metals are powerful reducing agents (meaning they really want to be oxidized) that reduce h2o and release h2(g). They form strong bases in aqueous solutions: 2m + 2h2o 2moh + h2, note: these metals" oxides can also dissolve in water to give a basic solution, ex. Li2 + h2o 2li+ + 2oh: ex. 2na2o2 + h2o 4na+ + 4oh- + o2: ex. 4ko2 + 2h2o 4k+ + 4oh- + 3o2: reactions with n: only li reacts with n at room temperature, 6li + n2 2li3n, reactions with halogens: forms ionic halides, 2m+x2.
