An element belongs to group 9. what common name might be used to describe the group to which this element belongs?

Explanation:

According to the periodic table chart, elements present in groups 3 to 12 are placed at the center.

These elements are known as d-block elements and all these elements are metals. General electronic configuration of d-block elements is .

These d-block elements are also known as transition elements. For example, elements of group 9 are Co, Rh, Ir etc.

Therefore, we can conclude that common name which might be used to describe the group to which this given element belongs is transition metals.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
