Sulfur will float, and iron will sink because each will retain its properties.
“Iron will float, and sulfur will sink because each will lose its properties” is <em>incorrect</em>. A substance will lose its properties only if it reacts to form a new substance.

The shape of the sp3 orbitals is tetrahedral.
<h3>What are orbitals?</h3>
The term orbital refers to a region in space where there is a high probability of finding the electron. We know that sometimes orbitals could be combined in order to obtain the orbitals that are suited in energy to participate in chemical bonding. This is known as the hybridization of orbitals.
The sp3 orbital is a hybrid orbital The four hybrid orbitals are directed towards the corners of a regular tetrahedron. Hence the shape of the sp3 orbitals is tetrahedral.
