3.The electron affinity of is zero.
4.
Explanation:
1.
<u>Electron affinity:</u>
It is defined as the amount of energy change when an electron is added to atom in the gaseous phase.
The electron affinity of is as follows.
2.
<u>Ionization energy</u>:
Amount of energy required to removal of an electron from an isolated gaseous atom.
The third ionization energy of Titanium is as follows.
3.
The electronic configuration of Mg:
By the removal of two electrons from a magnesium element we get ion.
has inert gas configuration i.e,
Hence, it does not require more electrons to get stability.
Therefore,the electron affinity of is zero.
4.
The ionization energy of is follows.
