Question

What is transition elements? explain their magnetic and catalytic properties.

Answer 1

Answer:

d block elements called transition elements.

Explanation:

magnetic properties :- 1.they show paramagnetic behaviour due to the presence of 1 unpaired electron in d shell.

2. magnetic properties increase with decrease in no. of unpaired electron.

magnetic property inversely proportional to the unpaired electron

catalytic properties :- 1. this is due to presence of vacant (empty ) d orbital.

2. they have ability to show variable valency.

3.they have tendency to form complex compound.
