Describe the properties of d and f block elements with full explaination??​

Answer 1

$\large\text{\fcolorbox{aqua}{yellow}{\red{Answer:-}}}$

PROPERTIES OF D-BLOCK ELEMENTS - DEFINITION

Following are the general properties of d-block elements.

These are metallic in nature

They are hard and have high densities

They have high melting and boiling point

They shows variable oxidation states

They form coloured ions and compounds

The atomic radii decreases with increase in atomic number.

PROPERTIES OF F-BLOCK ELEMENTS - DEFINITION

Following are the general characteristics of f-Block Elements.

They are paramagnetic in nature

Number of radioactive elements is more than the other blocks

They show variable oxidation states

They show shielding effect. Shielding is when an electron becomes less attracted to an atom the further it is away from the nucleus. This is because the forces holding atoms together become weaker as distance increases.

Answer 2

Answer:

• These are metallic in nature.
• They are hard and have high densities.
• They have high melting and boiling point.
• They shows variable oxidation states.
• They form coloured ions and compounds.
