Question

PROPERTIES OF F BLOCK ELEMENTS. ​

Answer 1

They are heavy metals.

They generally have high melting and boiling points.

They exhibit variable oxidation states.

They form coloured ions.

They have the tendency to form complex compounds.

Actinoids are radioactive in nature.

Answer 2

❥ F BLOCK ELEMENTS :

✤ F-block is broadly categorised into two series that is Lanthanides and Actinides .

✤ F-block separates s block and d block .

✤ F-block elements are also known as inner transition elements .

✤ F-block elements are placed separately at the end or bottom of the period table .

❥ PROPERTIES :

LANTHANIDES

✤ Lanthanides are soft metals .

✤ Melting point ranges from 1000k - 1200k .

✤ Good conductors of heat and electricity .

✤ They do not have radioactive nature .

ACTINIDES

✤ Appear silvery in colour .

✤ They have radioactive nature .

✤ These metals are highly reactive .

✤ General oxidation state is +3 .
