Question

What can the vast majority of elements in the periodic table be classified?

Answer 1

One useful way is by metals, nonmetals, and metalloids. (See also The Periodic Table: Families and Periods.) Most of the elements on the periodic table are classified as metals.

Answer 2

I may need a bit more information to answer your question, but try these out:
 
The vast majority of elements in the periodic table are metals, meaning they have some degree of ductility and malleability, if you are being asked about physical properties.

The vast majority of elements in the periodic table are also solids at room temperature, if you are being asked about phase.
