# What is the maximum number of hybrid orbitals an atom can have? [closed]

What is the maximum number of hybrid orbitals and atom can have? It is usually seen that an atom does not have more than 6 hybrid orbitals. Why is it so?

• What about hydrated salts of lanthanides? For example, $\ce{[Eu(H2O)9]^{3+},[ReH9]^{2-}}$ – Zenix May 3 at 11:44

The number 6 relates to a central atom in a molecule with octahedral geometry such as sulfur hexafluoride. $$\ce{SF6}$$
