In short, the ions are so arranged that the positive and negative charges alternate and balance one another, the overall charge of the entire substance being zero. What is the similarities between ionic and hydrogen bonds? The Because it has one more proton than electron, it has a charge of 1+. The chlorine has gained an electron, so it now has one more electron than proton. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). Potassium oxide can be produced by reacting potassium with oxygen and treating the resulting potassium peroxide with metallic potassium. Calculate the force exerted on the wall, assuming the water's horizontal momentum is reduced to zero.
