What does a "metalloid" mean on the periodic table?

An element that has characteristics of both metals and nonmetals

What is true about the following element considering its Lewis Dot Structure?

This has a full valence electron shell, so it will not bond with anything

What is true about the following element and its place on the periodic table:

All elements after Hydrogen will have larger atoms

Why are valence electrons important?

They help us understand what other elements an atom can bond with
