    Nucleus usually un-involved Atoms are  not  indestructible. The phrase “splitting of atom” refers to  phenomena involving the nucleus. For most everyday phenomena  the nuclei of atoms remain intact atoms may lose electrons to other atoms atoms may gain electrons from other atoms atoms may share electrons with other atoms

    Ions Every atom is  electrically neutral  --- this  means equal number of protons (+) and  electrons (-). If an atom loses or gains electron(s), the  result is an ION. Cation = positively-charged ion = due to  loss of electron. [Pronounce: cat-eye-on] Anion = negatively-charged ion = due to  gain of electron. [Pronounce: an-eye-on]
