Metals, metalloids, and nonmetals

[Lauryn Shinno 2H]

Hi can someone explain how you know if an element is a metal, metalloid, and nonmetals? Also, do we have to know this?

you should know by the placement on the periodic table. just search it up and youll find images! when i went to the periodic trends review session the ta said we should know stuff like that

Basically, the elements in the s, d, and f blocks (except H & He) are metals. As you get towards the right side of the table, the elements are mostly nonmetals. Between the metals and non-metals, there is a diagonal pattern of metalloids (B, Si, Ge, As, Sb, Te, Po). It's easier to see with a photo, but if you just google "periodic table metals, nonmetals, metalloids" you'll find one.

You should be able to tell by where the element is on the periodic table! I can't really remember off the top of my head, but metals are the left side, the d-block, and the f-block, nonmetals are on the right side, and metalloids are some of the elements between the d-block and the nonmetals. Google will definitely give you a better answer though haha
