Question

transition elements and there properties​

Answer 1

Transition elements are those elements which have incompletely filled d-subshell in there ground state or in any of there oxidation state.

There are 4 rows of 10 elements which involves filling of 3d, 4d, 5d and 6d orbits.

Properties:-

1) They have variable oxidation state.

2) They have high melting point and boiling point.

3) They are electropositive in nature.

4) They have tendency to form complexes.

5) All transition elements have typical metallic properties.

Answer 2

Answer:

Properties of transition elements include:

have large charge/radius ratio;

are hard and have high densities;

have high melting and boiling points;

form compounds which are often paramagnetic;

show variable oxidation states;

form coloured ions and compounds;

form compounds with profound catalytic activity;
