00:25
And that's in group two, second column.
00:28
And this is part of the alkaline earth metals.
00:30
So this entire orange column is the alkaline earth metals.
00:34
And if you look in your book at table 4 .4, you can see that magnesium is a macromeneral, and it is part of your bones, and it is important in your metabolism.
