Chemical elements? Wel, biscuits are mostly made of flour and water. Flour is mostly carbohydrate, which (as the name implies) is carbon (C), hydrogen (H) and oxygen (O). There will undoubtably be some protein, too, and protein consists of those elements plus nitrogen (N). Water is hydrogen and oxygen. So for the most part a biscuit, or any food, or any organic material at all, will be C, H, O and N. However, there will be lots of other elements in low concentrations. Proteins contain small amounts of sulfur (S) and phosphorus (P). The cook probably added salt (NaCl), so that gets you sodium (Na) and chlorine (Cl). Perhaps the flour was enriched, in which case some of the vitamins and minerals have metals associated with them, like zinc (Zn), cobalt (Co) and iron (Fe). Biscuits often use baking powder, and baking powder usually contains aluminum (Al). There are some other elements that are so common at the surface of the Earth that they are likely to sneak in, e.g. through tiny contaminants, like magnesium (Mg), calcium (Ca), potassium (K), silicon (Si), and fluorine (F). Technically the biscuit contains air, in little pockets, and air is about 1% argon (Ar).
