When we eat nitrates, they are converted into nitrites in our digestive system, which are then converted to ammonia and disposed of by the body. Nitrites are also inorganic compounds made up of nitrogen and oxygen, but instead of three oxygen molecules they have two, NO2. Nitrates are not generally harmful unless they are consumed in massive quantities. Nitrites, on their own and in moderation, are also generally not harmful.
This chemical compound is composed of one tin ion, which is ionically bound to two NO3, or nitrate ions. The tin (II) ion has a 2- charge. Nitrate is a polyatomic ion with a 1- charge. Nitrate has a trigonal planar geometry, with a central nitrogen atom and three surrounding oxygens. The nitrogen atom carries a 1+ charge, while the three oxygens carry a 2/3- charge. Nitrate carries an overall 1- charge.
