an atom of cesium (Cs), atomic number 55, loses an electron to an atom of fluorine, (F) atomic number is 9, what kinds of particles are formed by this transfer of a negatively charged electron? Is a chemical compound formed? if so, what is it called??
Homework Answers
cesium (Cs) by losing one electron, it is converted to Cs+ ion and fluorine (F) by accepting that electron, it is converted to F- ion. These two positive(Cs+) and negative(F-) ions combine to form Ionic compound.Name of the compound is Cesium fluoride(CsF).
