Post-Transition Metals Element Group Poster and similar items

Post-transition metals are a set of metallic elements in the periodic table located between the transition metals to their left, and the metalloids to their right. Physically, post-transition metals are soft (or brittle), have poor mechanical strength, and have melting points lower than those of the transition metals. Our non-paper poster material is waterproof and tear resistant. It is meant to last a lifetime and can even be used outside. This option does not come with frame. Custom orders accepted.
