Atoms from which two elements would form ionic bonds

A metal and a non-metal would exchange electrons with each other and become what is known as an ionic bond. Such as NaCl, Na+ which is a metal ion of the 1a group, and Cl- which is a non metal ion of the 7a group.

So atoms from elements in which there is a metal and a non metal would form an ionic bond.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
