Manganese (new) - Periodic Table of Videos

manganese is actually a much more interesting metal than you might expect i should say element pants the metal
so first thing we need to do is like the Bunsen so there we are
ok and then what we've got inside the boiling tube is actually potassium permanganate
it is one of the transition metals and the road transition metals stretches all the way from scandium over here to zinc over there
what makes manganese particularly interesting is that it is in the middle of this transition group
there are 10 transition metals from scandium to zinc and manganese is number five the reason they're 10 is because each of them has a certain number of D
electrons 14 scandium 10 for zinc so manganese in the middle has five and five if you're mathematician you will know is half ten so it has exactly half
the number of the electrons that can be accommodated in the cell all I've done is just popped a couple of spatulas
of potassium permanganate into the boiling tube and as you can see from the colors are very very dark almost black
possibly a dark green so that's in there but let's begin just having look at the metal itself this is about the manganese that
