Are halogens and non-metals metal or non-metals?

Question

I think they're both non-metals

Answer 1

You're right but I don't quite understand why you ask such a question.
Halogens are non-metals (all of them are non-metals)
Non-metals must be non-metals (or they wouldn't be called that).

Answer 2

Ugh. >.<

I meant to ask noble gases. I don't know why I ask if non-metals are non-metals.

The reason for that is one of the noble gases (astantine) is said to be metalloid, so not sure what to clssufy noble gases as.

Answer 3

Noble gases are non-metals; however, astatine is not a noble gas. It is a halogen. Most articles I have read emphasize that there is some evidence for it to be a metal, some as a non-metal, and some as a metalloid. Most also emphasize that with such limited data we can only guess. On the other hand, most of the periodic charts I have looked at lately include At at the bottom of the "stairway of the elements". With regard to that placement, it must be on the immediate right or on th immediate left of that staircase line. In my opinion, no matter how you slice it, At is either on the right side or on the left side of that line and all elements adjacent to the line are metalloids in which they sometimes act as a metal and sometimes as a non-metal. I think based on this reasoning I would classify it as a halogen with metalloid characteristics, at least until more data is presented and the issue is clarified.
