Question

What is the trend of ionization enthalpy in d block elements?

Answer 1

Answer:

Ionization enthalpies for a given element increases from the first ionization enthalpy, IE1 to the third ionization enthalpy, IE3. iv. The atoms of elements of the third transition series possess filled 4f-orbitals. 4f orbitals show a poor shielding effect on account of their peculiar diffused shape.

Answer 2

Answer:

$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$
