Question

simple use d and f block element​

Answer 1

Answer:The d-block of the modern periodic table consists of elements of the groups 3 to 12 in which the orbitals consist of progressively in each of the four long periods. the elements constituting the f-block is those elements in which the 4f and 5f are progressively in the later of the two long periods.

These elements are actually formal members of the group three from which they have been taken out to form a seperate f-block of the periodic table.

The d-block elements acquire the name of transition elements as they represent a significant change in properties from highly electropositive s-block elements to the least electropositive p-block elements.

Uses Of F block elements:

some applications of the f block elements are:

.Lanthanide alloys(mischmeyal)

.the f block elements are also called inner transition metals which are also known as the lanthanides and actinides. they also meet this criterion because the d orbital is only partially occupied before the f orbitals.

.Lanthanum and actinium are generally both accepted as f-block elements. you will notice in the royal societys periodic table, La and Ac are both color coded to match the other f-block elements.
