to which side of a water molecule are these attracted? magnesium sulfur iron chlorine potassium bromine…

Brief Explanations:

Water is a polar molecule with a partial - negative oxygen end and partial - positive hydrogen ends. Cations (positively - charged ions) are attracted to the oxygen (partial - negative) side of the water molecule, and anions (negatively - charged ions) are attracted to the hydrogen (partial - positive) side. Metals form cations and non - metals (except noble gases) can form anions. Magnesium, iron, potassium, calcium are metals and will form cations, so they are attracted to the oxygen side. Chlorine, sulfur, bromine, nitrogen are non - metals and can form anions, so they are attracted to the hydrogen side. Helium is a noble gas and has little interaction with water in this context.

Answer:

Magnesium: Oxygen side Sulfur: Hydrogen side Iron: Oxygen side Chlorine: Hydrogen side Potassium: Oxygen side Bromine: Hydrogen side Calcium: Oxygen side Helium: Little interaction Nitrogen: Hydrogen side
