About This Product
The model lets students hold the phosphorus tetrahedron and see how fixing four atoms into such a tight shape forces small bond angles and creates strain. It supports lessons on allotropy, molecular geometry and VSEPR theory in structural and inorganic chemistry.
Frequently Asked Questions
Does the Structure of Phosphorus Model need a stand?
No. The tetrahedral structure is self-supporting, so no base is required.
What are the parts made of?
The spheres are high-density polypropylene and the connectors are polycarbonate.
