The rapid decreases in 5V as TMD, FeSc or host material is added to the metal-ammonia, 10 suggest that the fraction of solvated electron is radiply decreasing. This means that these free solvated electrons started to immigrant to host-samples valence band or fermi band(see section 2.3.1) after that the guest spicies are nestled in the centers of the crystal structure of host spicies. The intercalation of metal-ammonia (if this clari cation is correct) enhances the lattice match, thereby advancing the intercalation process.To enhance the lattice match, the ions size of guest-material and the d-spacing or c0 of host-guets should be proportional to each others. Thus, the rst one(ioniserted guest material) should be smaller than the later one, host-material. Ions size may be larger or smaller than the neutral atom, contin- gent upon the ion 's charge. At the point when an atom loses an electron to edge a cation, the lost electron no more contributes to shielding other electrons from the charge of the core; thus, alternate electrons are all the more rmly pulled in to the core, and the diameter of the ion decreases. So also, when an electron is added to an atom, framing an anion, the added electron shields alter- nate electrons from the nucleus, with the outcome that the extent of the atom increments[7]. In this report, the ion 's size was estimated by using X-ray 's data and table 2 in section 2.3 con rms the values of di erent guest-samples. The second element that is crucial
