Are group 7 metals or non metals?

Answer 1

Metals.

But I'd rather you learnt more from my answer so hear me out. Get your Periodic Table and lay it out in front of you. Find Boron (B), it's on the right hand side, on the left of the sticky up bit. Got it? Draw a thick pencil mark underneath it. Now go down in a zig zag pattern drawing a line between Aluminium (Al) and Silicon (Si), underneath Silicon and down between Germanium (Ge) and Arsenic (As) etc.

Done it? All the elements on the left hand side of that line are metals. All the elements on the right hand side are non-metals. There are way more metallic elements than non-metallic ones. It's only because compounds are non-metallic that we have so many non-metals in our world.

A word of caution. Some periodic tables put Hydrogen (H) at the top of the first column. Others have it floating above the whole table, completely separate. That's because Hydrogen is an odd one out. Technically it belongs in the first column; it's reactive, it's unstable, it has just one outer electron. However, it's not a metal. So it doesn't really fit there. Hence the 'floating' versions of the table. If you remember the zig zag and that H is the odd one out you'll be ok.

Answer 2

Group 7 are transition metals (Manganese group)

manganese (Mn), Technetium (Tc), Rhenium (Re), Bohrium (Bh) all are metals.

By the way, don't mix this up with the Fluorine group (Halogens) which are nonmetals, their group number is 17 (seventeen i.s.o. 7)

Answer 3

All the elements in group 2 are metals, so there are no non-metals in group 2 of the periodic table.
