Answer 2

`\boxed {\boxed {\sf 1. \ Antimony}}`

Step-by-step explanation:

A metalloid is an element that is "in between" a metal and non-metal. They display some properties of both.

On the Periodic Table, the metalloids are found in a zig-zag step pattern to the right of the metals and the left of the non-metals.

There are 7 metalloids: boron, silicon, germanium, arsenic, antimony, tellurium, and polonium.

So, the correct answer is 1. Antimony
