how are cations formed give
give an example

Answer 1

What Is a Cation?What do a battery, your heart, and fertile soil have in common? Answer: All of these require cations in order to work.But let's get a little more specific. Have you ever gulped down a sports drink after becomingdehydrated from physical activity? Maybe a trainer, gym teacher, or even a sports drink commercial told you that consuming the beverage would help you replace your electrolytes. Anelectrolyteis a solution that contains ions. And in drinking that sports drink, you have consumed cations. But what is a cation?Acationis a positively charged atom. As you may know, an atom is electrically neutral. This is because the number of protons and the number of electrons in an atom are equal, and the charges balance out. When an atom forms a cation by losing one or more electrons, it now has moreprotons, or positively charged particles, thanelectrons, or negatively charged particles.Here, you can see all this in action. When sodium loses an electron, the resulting cation has a +1 net positive charge. Similarly, when calcium loses 2 electrons, the resulting cation has a +2 net positive charge.
