In a neutral solution the concentration of in a neutral solution the concentration of water molecules is less than the concentration of hydrogen ions hydrogen ions is greater than the concentration of hydroxide ions hydrogen ions is less than the concentration of hydroxide ions water molecules is less than the concentration of hydroxide ions hydrogen ions is equal to the concentration of hydroxide ions

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
