True: due to
<span>- A stock solution is a solution that has been prepared with a greater concentration of solute than is needed for a procedure, so it must be diluted to the proper concentration(s) before use.
- It is very important that you master the concepts and techniques of preparing dilutions .
- A dilution is made by taking a measured portion of a stock solution, and adding to it a solvent (water or a buffer).
- This creates a new solution with a lower concentration of solute than was contained in the stock solution.
- Since the solute concentration of the stock solution is known as well as the volumes of stock and solvent, it is possible to calculate the concentration of solute in the dilute solution.
- The dilute solution is always less concentrated than the stock or starting solution.

Answer:
Ionization energy is the energy required to remove an electron away from an atom, which can be written as IE. ... Electron affinity, on the other hand, is the energy released when an electron is added to the atom. On the periodic table, electron affinity usually decreases down a group, and increases across a period.
