Fun fact: Calcium is the most abundant mineral in the body, and is found naturally in a wide variety of foods and beverages and added to many others! (Hellooo orange juice.) But whether lactose-intolerant or sick of wine and cheese parties, there’s no need to rely only on dairy products for that daily dose of calcium. Here’s why we should get enough calcium—and all the unexpected ways to get enough of it. Beyond the Dairy Aisle—The Need-to-Know It’s no secret that calcium is vital for strong bones and teeth , but it goes beyond that. This mineral also helps the body maintain healthy blood vessels, regulate blood pressure, and even prevent insulin resistance (which could lead to Type 2 diabetes) . Adults should consume about 1,000 mg of calcium per day (which translates to about one glass of skim milk, one thick slice of cheddar cheese, and one cup of plain yogurt), yet most Americans still fail to meet the mark. According to one survey , only 16 percent of females ages 20 t...
Copyright: wiredcosmos When you view an atom, the first question you might ask is ‘what kind of atom is it?’ What you are really asking is ‘which element am I looking at?’ You can answer this by counting the number of protons in the atom. The number of protons , neutrons and electrons is the same in a neutral atom- that is, an atom with no charge. So, in a regular Calcium atom, there are 20 protons, 20 neutrons and 20 electrons. The electrons orbit around the nucleus and have a negative charge. An isotope is a version of the element with a different number of neutrons. When the number of protons differs from the number of electrons, you have an ionic charge. A Calcium atom with 20 protons and 18 electrons has a charge of 2+ because it has 2 extra protons, which have a positive charge. A charged atom is called an ion . When the charge is positive, it is called an cation . If the Calcium gained two more electrons it would have a charge of 2- because it has ...
