So well, I'm kinda exploring other genres of metal and I was wondering if you guys know some good folk/viking metal, already know of Ensiferum (epicness) and Wintersun (same story).
They react vigorously with water...vigour increasing down the group.
Group 1 metals react with group 17 non metals because group 1 metals donates one valence electron to group 17 non metals that are missing one valence electron, to form an ionic compound.
