Indicate the type of hybrid orbitals used by the central atom in tef4

Explanation:

Hello,

The type of hybrid orbitals used by the tellurium could be found via the following formula:

In this case, tellurium has six valance electrons and four monovalent bonds (those four fluorines), thus:

Such result, indicates a hybridisation which accounts for one ‘s’, three ‘p’ and one ‘d’ orbitals of almost equal energy which give five identical and degenerated hybrid orbitals arranged in trigonal bipyramidal symmetry.

Best regards.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

lol for the pointsss
