Please be kind enough to include some examples too in the answer.
When it becomes an ion, it loses 3 electrons, leaving behind only 10Thus the remaining aluminum ion is said to have a net positive charge of 3, sign (or the minus sign, in the case of a negatively charged ion) before or after the numberatom gains electrons, acquiring a negative chargeSorry not sure about it :))
Carbohydrates are found in a wide array of foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pieThey also come in a variety of formsThe most common and abundant forms are sugars, fibers, and starches The basic building block of every carbohydrate is a sugar molecule, a simple union of carbon, hydrogen, and oxygenStarches and fibers are essentially chains of sugar moleculesSome contain hundreds of sugarsSome chains are straight, others branch wildly Carbohydrates were once grouped into two main categoriesSimple carbohydrates included sugars such as fruit sugar (fructose), corn or grape sugar (dextrose or glucose), and table sugar (sucrose)Complex carbohydrates included everything made of three or more linked sugarsComplex carbohydrates were thought to be the healthiest to eat, while simple carbohydrates weren’t so greatIt turns out that the picture is more complicated than that The digestive system handles all carbohydrates in much the same way—it breaks them down (or tries to break them down) into single sugar molecules, since only these are small enough to cross into the bloodstreamIt also converts most digestible carbohydrates into glucose (also known as blood sugar), because cells are designed to use this as a universal energy source Fiber is an exceptionIt is put together in such a way that it can’t be broken down into sugar molecules, and so it passes through the body undigestedFiber comes in two varieties: soluble fiber dissolves in water, while insoluble fiber does notAlthough neither type nourishes the body, they promote health in many waysSoluble fiber binds to fatty substances in the intestines and carries them out as a waste, thus lowering low-density lipoprotein (LDL, or bad cholesterol)It also helps regulate the body’s use of sugars, helping to keep hunger and blood sugar in checkInsoluble fiber helps push food through the intestinal tract, promoting regularity and helping prevent constipation.
