WebA cation is a positively charged ion with fewer electrons than protons. Anion. An anion is a negatively charged ion with more electrons than protons. Cations and anions are measured by their ionic radius and they differ in relative size. Cations are small, most of them less than 10 −10 m (10 −8 cm) in radius. In general, anions are larger ... WebCation is an ion (charged particles) that has a positive charge on it, whereas an anion has a negative charge on it. Atoms loose or gain electron in order to become stable, therefore they acquire positive or negative charge respectively. What are cations and anions Class 8? Cations gain electrons and convert into neutral atoms or molecules.
WebExamples of antiaromatic compounds are pentalene (A), biphenylene (B), cyclopentadienyl cation (C).
