Answer 2

Answer:

Transition metals: (a) Their compounds are generally coloured

(b) They can form ionic or covalent compounds

(c) They do not exhibit varialbe valency

Explanation:

Step 1: The majority of transition metals are not diamagnetic. The majority of transition metals exhibit paramagnetic or ferromagnetic properties. It is because their atoms or ions contain unpaired electrons.

Step 2: Many of the compounds made up of transition metals exhibit paramagnetic behaviour. The transition metals have high enthalpies of atomization. Transition metal complexes typically take on a colour. Catalysts made of transition metals and their many compounds work well.

Step 3: Variable valency is seen in transitional components. The higher number of (n-1)d electrons involved in the interatomic metallic bonding, in addition to the ns electrons, is what is thought to be responsible for the high melting points of these metals.
