Which of the following is an example of anionic interference in atomic emission spectroscopy? O Interference of high concentration of sodium ions in assay calcium ions. Interference by formation of less volatile salt with sulphat by calcium. Decreased drop size of the analyte solution by alcohols.

Design an alcohol with six carbons, where the hydroxyl group is on the third carbon.

A metal is considered reactive if it easily loses electrons to achieve a stable octet. Would you prefer metal that readily loses electrons? How is this related to the metal's ionization energy? Would it be better for the metal to have high or low ionization energy?
