All the remaining statements are correct.
The hydroxide ions keep decreasing and the hydrogen ions increase, pH decreases.
<h3>What is hydroxide?</h3>
Hydroxide is a diatomic anion with synthetic recipe OH⁻. It comprises of an oxygen and hydrogen particle kept intact by a solitary covalent bond, and conveys a negative electric charge. It is a significant yet generally minor constituent of water. It capabilities as a base, a ligand, a nucleophile, and an impetus. Hydroxide is a diatomic anion with chemical formula OH −. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. Hydroxide ions can act as a catalyst in different types of reactions. Hydroxide ions can function as base, ligand, nucleophile or a catalyst.

Answer:
Most similar - Lithium
Least similar - Phosphorus
Explanation:
Rubidium is an element in group 1A of the periodic table. It is a metal and forms an ionic compound with chlorine. The formula of the compound is RbCl.
If we look at the options, Lithium is also a group 1A element and forms an ionic compound with chlorine having the formula LiCl which is very much similar to RbCl chemically.
Phosphorus is a nonmetal. Its compounds with chlorine, PCl3 and PCl5 are covalent and does not resemble RbCl in any way.
Maybe by protons i forgot how to spell it :(
