Question

write the characteristics of d block elements
​

Answer 1

Answer:

Explanation:

1. They show variable oxidation states.  

2. They form coloured ions.  

3. They are used as catalyst.  

4. They form alloys.

Answer 2

Answer:

D block elements form stable complexes which are often paramagnetic. D block elements have variable oxidation state and can form coloured compounds. They have high melting and boiling points and contain large charge to radius ratio.

Explanation:

Group 3-12 are called D block elements. They are also called transition elements. Their outermost electron goes to the d subshell. Due to d-d transitions they form stable coloured complexes. The presence of d electron gives them unique properties. D block elements show properties between those of s block and p block elements.
