WebIn ionic compounds, electrons are completely transferred from one atom to another so that a cation—positively charged ion—and an anion—negatively charged ion—form. The strong electrostatic attraction between adjacent cations and anions is known as an ionic bond. WebDades: m e = 9, 11 × 10 − 31 k g; Q e = − 1, 60 × 10 − 19 C . Solució.
