Question

what do you mean by anomalous behaviour and anomalous properties give general definition of anomalous in respect of chemistry

Answer 1

Anomalous behavior is the unique behavior of the element with respect to other elements of the same group. It's unique properties are anomalous properties.

Answer 2

Anamaolous behaviour is the different behaviour shown by an element of a group. It has anamolous properties i.e., properties different from its group.

Explanation:

• Anamolous behaviour is defined as the abnormal behaviour off the elements present in a group due to their small size, electronegativities, and non-availability of d-orbitals.
• The elements which belong to a group should show same properties, but some show different properties known as Anomolous properties.
• For example beryllium, it is covalent as compared to other alkaline earth metals. It does not react with acid, and it has high melting and boiling points.
