Atomic Orbital Set
Product Code : EL-MM-11005
Quick answer: The Atomic Orbital Set is a set of 14 self-assembly orbital models for teaching the shapes of s, p and d atomic orbitals and sp, sp2 and sp3 hybridisation. Pink and purple lobes mark the positive and negative wave phases, and each model stands on its own transparent base. Lab Exports supplies it as a reseller to schools, colleges and universities.

How the model set is used in teaching
An atomic orbital is the region around a nucleus where an electron is likely to be found, and its shape is hard to picture from flat diagrams. The set lets students hold each shape: the spherical s orbitals, the three dumbbell-shaped 2p orbitals at right angles along the x, y and z axes, and the five 3d orbitals. Pink and purple pear-shaped lobes show the two wave phases, positive and negative, which matter when orbitals overlap to form bonds.
The hybrid models show what happens when an s orbital mixes with p orbitals. sp hybrids point in opposite directions at 180 degrees, sp2 hybrids lie in a plane at 120 degrees, and sp3 hybrids point to the corners of a tetrahedron at about 109.5 degrees, which explains the shapes of ethyne, ethene and methane.
The 2s + 3 x 2p model places all four second-shell orbitals together, so students can compare it with the sp3 model formed from the same orbitals after hybridisation.

Frequently asked questions
What do the pink and purple lobes on the orbital models show?
They show the two wave phases, positive and negative, of the p and d orbitals, which decide how orbitals combine when bonds form.
Which orbitals does the atomic orbital set include?
1s, 2s, three 2p and five 3d unhybridised orbitals, a combined 2s + 3 x 2p model, and sp, sp2 and sp3 hybridised orbitals, 14 models in all.
