Helium has the lowest freezing point of all the elements. When coming to metals, mercury has the lowest freezing point of all the metals.

The relationship between a cathode and an anode involves the transfer of electric charge between them. The cathode is the negative terminal on the battery, which has zero electric potential. The anode is the positive terminal on the battery and has the battery's maximum electric potential. Current flows from the battery's anode (positive terminal) to the cathode (negative terminal). In electron flow, electrons leave the negative side of the battery and move towards the positive side of the battery.

Hence, The relationship between a cathode and an anode involves Electrons.

The reactivity of an atom arises from the existence of unpaired electrons in the valence shell.

The basic concept in economics is that all resources are limited.

The ryots came to see the moneylender as devious and deceitful. They complained of moneylenders manipulating laws and forging accounts.

This law was meant to check the accumulation of interest over time. The moneylender, however, turned the law around, forcing the ryot to sign a new bond every three years.
