An organelle could be the nucleus of a cell.
The nucleus of a cell would be comparable to the nervous system in the body, which is considered an organ system.

KCl is an ionized salt which readily dissolved in water and generate potassium and chloride ions. In which potassium posses one unit positive charge and chloride posses one unit negative charge. As water is a polar solvent there are partial positive and negative charge on the hydrogen and hydroxide ion respectively. The high solubility of the potassium chloride (KCl) in water is due to the stabilization of the ions in the polar solvent. The solvation of the ions can be shown as-
In the Lewis structure of PO43- there are a total of 32 valence electrons. For the Lewis structure for PO4 3- you should take formal charges into account to find the best Lewis structure for the molecule. Remember, PO4 3- has a negative three charge on the molecule.
