Why is calcium a metal? Why does it seem to have so …
Elemental calcium is indeed a metal, although a reactive one that tends to oxidize in air because of reaction with oxygen. The Ca 0 metal is not found often in nature for this reason. The "calcium" we talk about when we think of calcium scale on pluing is calcium carbonate , and other calcium salts.
Chemistry Blog: Lab Report: Metal or Nonmetal Lab
For this lab experiment, our new group, The Acids, tested sample elements A-G with the hopes in gaining enough knowledge to characterize each sample as a metal, a nonmetal, or a metalloid. To prepare for the simple, yet tedious procedure, we placed each of the seven elements on a piece of paper, and labeled them to prevent confusion.

Nonmetal | Encyclopedia
All of the halogens tend to form salts, compounds — formed, along with water, from the reaction of an acid and base — that bring together a metal and a nonmetal. Due to this tendency, the first of the family to be isolated — chlorine, in 1811 — was originally named "halogen," a coination of the Greek words halos, or salt, and gennan, "to form or generate."
