Solution
The increase in the first six ionisation energies of Te can be attributed to two main factors:
-
Increased Nuclear Charge: After each successive ionisation, an electron is removed, reducing the electron-electron repulsion and making the remaining electrons more attracted to the nucleus. This means that more energy is required to remove each successive electron.
-
Electron Shielding: The inner shell electrons 'shield' the outer shell electrons from the full effect of the nuclear charge. As you remove electrons, the shielding effect decreases, making the remaining electrons more strongly attracted to the nucleus. This also means that more energy is required to remove each successive electron.
