Lanthanides and actinides are what kind of metals? inner-transition alkaline earth alkali transition is alkaline earth right

Lanthanides  and actinides are  inner  transition

   Explanation

Lanthanides and actinides  are  known as  inner  transition  element  because they are located   at the bottom of periodic  table.

Lanthanide elements are element  which atomic number ranges between 58-71 and they fill  their  4F sub level  progressively.

Actinides elements are  elements which atomic number  ranges  between 89 -103  and  they fill their 5f  sub level  progressively.

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.
