Expert Answer. But corrosion by caesium on spacecraft components has pushed development in the direction of inert gas propellants, such as xenon, which are easier to handle in ground-based tests and do less potential damage to the spacecraft. Selenium -Se Both chlorine and oxygen are nonmetals and will form anions (ions with a negative charge) because they are gaining electrons in an ionic compound. So in general, we can predict that any metalnonmetal combination will be ionic and any nonmetalnonmetal combination will be covalent. J. von Schnering, Catenation of Phosphorus Atoms, Chap.
