Question

What are the characterstics of d and f block elements?​

Answer 1

Answer:

PLEASE MARK AS BRAINLIEST.

Characteristics of F block elements-

1. Elements in which the last electron enters in the f subshell of the antipenultimate shell are f block elements.
2. Also called inner transition elements.
3. They are all heavy metals.
4. They also form complex salts.
5. They show variable oxidation states.
6. Their compounds are generally coloured.

general characteristics of D block element

1. Metallic nature: as the number of electrons in the outermost shell is very less i.e.
2. Melting and boiling points: They show very high melting and boiling points.
3. Atomic radii: a great degree of variation is seen in the atomic radii across each transition series.
4. Ionic radii: The ionic radius is similar to the pattern of atomic radii.
5. Atomic volume and Densities: the atomic volume of transition elements is much lower than those of S and P block elements.
