09:05 The d-block elements in the periodic table have their last electron in the outermost d-orbital. 18:10 D-block elements have a U-shaped electronic configuration and exhibit various metallic properties. 27:15 The trend of melting point and boiling point of transition metals is that it increases and then decreases, with a maximum point in the middle. Exceptions include manganese and Tc. 36:20 The atomic size trend from left to right in the periodic table is influenced by Z effective and screening effect, while the trend down the group is affected by lanthanide contraction. Ionization enthalpy generally increases from left to right, with some exceptions. 45:25 Second ionization enthalpy of chromium and copper is high due to their stable electronic configurations. Third ionization enthalpy of manganese is high as well. Nickel, copper, and zinc have high third ionization enthalpy, explaining why they do not have more than 2 oxidation states. 54:30 The trend of standard electrode potential shows that as we move from left to right in the first series, the value becomes less negative, except for certain exceptions in the case of copper, manganese, nickel, and zinc. 1:03:35 Fluorides stabilize higher oxidation states in halides, while other halides undergo hydrolysis and form Oxohalides 1:12:37 D-block elements form colored ions and complex compounds due to unpaired electrons in their d-orbitals.

(!) Zinc, cadmium and mercury are colourless because :- 1 -->They have fully filled d-orbital -->No unpaired electron is present i -->No d-d transition is possible. (2)Transition elements which show only one oxidation state - Scandium. (3)In 3d series which element has the highest oxidation state - Manganese.i (4)In D-Block, Which element has the highest oxidation state - Osmium, it shows +8 oxidation state. (5)Diamagnetic - When there is fully filled d-orbital, no unpaired electrons is present. Then it is diamagnetic. In Diamagnetic meu =0(always). (6)Paramagnetic - When d-orbitals are not fully filled, unpaired electrons are present. Then it is Paramagnetic.i (7)Formula foor Magnetic moment(denoted by meu) = root n(n+2) .1 Hope this will help u😊

Awesome
Answer for 50% of all questions asked from d-block is either "due to presence of unpaired electrons in d orbital" Or "Because it attains more stable electronic configuration"

Best of luck everyone for 27th feb👍🏼
Explanation with image help studying alot . Btw I love the teacher who explain this ❤️🔥
I most liked the way you explained screening effect with the use of curtains and visuality concept.
Excellent teaching Ma'am. I teach Organic chemistry to UG and PG students and always found inorganic chemistry boring. Honestly speaking you are a wonderful teacher. No one can teach D block better than the way you taught. Good work. Regards.
lol, day after tommorow is my chem boards 💀
Mam ne ye to btaya ki ye exception h par exception ke bare mai koi reason nhi diya...so it is important to study about exception....eg 24:55 there is a dip in between...which is not explained... Ans- it is due to stability of Mn due to half filled orbitals...so they do not participate in metallic bonding so less heat is required to convert 1 mole of metal lattice into free atom ..

Ma'am I think formation of colored ions is due to the transmission of the complementary color of the absorbed monochromatic light (due to d-d transition) while transitioning to excited levels and not due to the release of the absorbed energy. Btw, your teaching style is awesome. Thanks ma'am ❤️
Thank you so much mam..😍😊I was thinking of starting this chapter and here you are finally 🤩
