Do you mean where or why?


Let us look at the Table...


Now most of the 100 of so elements are METALS... The non-metals are confined to the RIGHT of the Table as we face it; there are 15 or so; the blue triangle, and the yellow and gold Groups. The elements that are pea-green in colour, boron, silicon, germanium, arsenic, etc. are metalloids. And these have intermediate properties with respect to metals and non-metals.
