-
chemical
reaction with water
react violently
example: potassium melts with the heat of the reaction, and the hydrogen catches on fire
H bubbles off, leaves solution of hydroxides= alkalis
-
-
-
similar reaction, very reactive, only need to lose one electron to be stable
noble gases
non-metal elements
elements
helium, neon, argon, krypton and xenon
-
unreactive
have an outershell of 8 electrons, except helium (2 electrons for 1 shell)
-
