Answer:
Charge-charge interactions (salt bridge, ionic bond) are electrostatic interactions between a pair of ions is True.
Explanation:
Electrostatic interaction between pairs of ions involves the transfer of ion/charges from two bonding elements in their ionic state
The isotopes of an element differ in the number or neutrons whereas the number of protons or electrons of a neutral atom stays the same. The molar mass of the element is based on the percent abundances of different isotopes and the individual molar mass of each isotope.
