I am doing a project for science. I need to find 20 products from my house that have one elements from the perodic table like iron, calcium, lithium, berylium, carbon, silicon, argon, neon, cobalt, lead, etc... I need to do this project by October 16, 2006. I need to do the project on 20 different elements. I have looked every where for elements but I cannot find any in the ingredients of the products. The product can be the pure sample of the element, compound, or mixture. My teacher prefers for the product to be pure. I need label as evidence that the product does have the element. I would really appreciate your help.
