    Polarisation Power
AI Thread Summary
Cations with electronic configurations of ns2 np6 nd10 exhibit greater polarization power on anions compared to those with configurations of ns2 np6. This increased polarization power is attributed to their smaller size, which results in a poorer shielding effect on outer electrons. Consequently, cations with the ns2 np6 nd10 configuration experience a stronger effective nuclear attraction, enhancing their ability to polarize anions. In contrast, cations with the ns2 np6 configuration have a greater shielding effect, leading to reduced nuclear attraction and, therefore, less polarization power.

Why the cations having electronic structure of ns2 np6 nd10 have more polarisation power on anions than the cations having electronic structure of ns2 np6?

Probably because they are smaller.

This due to the cations which have elctronic configuration ns2 np6 nd10 has a poor shileding effect on outer electrons hence effective nuclear attraction increase. The cations which have configuration ns2 np6 have a greater shielding effect so they have less nuclear attraction

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...

Thread 'Ruthenium-Iridium compound with catalytic effects'

Engineers slash iridium use in electrolyzer catalyst by 80%, boosting path to affordable green hydrogen https://news.rice.edu/news/2025/engineers-slash-iridium-use-electrolyzer-catalyst-80-boosting-path-affordable-green Ruthenium is also fairly expensive (a year ago it was about $490/ troy oz, but has nearly doubled in price over the past year, now about $910/ troy oz). I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
