  Do you have any good information i could use for my chemistry presentation on the element calcium. ill be sure to site you

Found by Sir Humphrey Davy in 1808. It makes up our bones. It is the fifth most abundant thing in the Earth's Crust. It burns with a yellow red flame. 50-75% of adults do not get enough calcium daily. it is found in limestone, gypsum, and fluorite. It is used for alloys, and cement for cunstruction. Calcium is found in broccoli, kale, dandelion greens, collard greens, almonds, sesame seeds, blackstrap molasses, beans, and fortified beverages such as soy milk and orange juice. Hope this helps! :)
