Question

1. what are the characteristics of metalloids?

Explanation:

Metalloids have properties intermediate between metals and non - metals. They can conduct heat and electricity to some extent (like metals), but not as well as pure metals. They are also brittle (like non - metals). Their chemical properties can vary, and they often show amphoteric behavior (reacting with both acids and bases).

Answer:

Metalloids have intermediate properties between metals and non - metals. They have some conductivity (less than metals), are brittle (like non - metals), and often show amphoteric chemical behavior.
