Metalloids are sandwiched between the metals and the nonmetals and have characteristics of the two.  They include B, Si, Ge, As, Sb and Te. 
Nonmetals have varying properties, however, there are some standard properties that can be observed.  These include:

Many nonmetals are gases or molecular or network solids at room temperature.  Bromine is an exception, being a liquid at room temperature                                          

Nonmetals are not malleable or ductile; they tend to be brittle in the solid phase

Solid nonmetals lack luster, and their surface appears dull

Nonmetals have high ionization energy and high electronegativity values

Nonmetals are poor conductors of heat and electricity

Nonmetals tend to gain electrons to become negative ions with radii larger than their atoms
