The <width> specification is on a row of its own, in the same column
that it is supposed to control. Try the following:

--8<---------------cut here---------------start------------->8---
#+ATTR_LATEX: :environment tabularx :width \textwidth :align lXl
| NAME   | CHARACTERISTICS      | EXAMPLES    |
|--------+----------------------+-------------|
|        | <20>                 |             |
| Metals | metallic bonding: adjacent atoms share electrons in a 
non-directional way; opaque, shiny, electrically conductive, they reflect 
photons, light rays from the Qenvironment | a metal pan |

--8<---------------cut here---------------end--------------->8---
