Ionic: electron transfer; Covalent: electron sharing.

The chemistry platform offers a comprehensive range of study materials, including videos, PDFs, questions, mind maps, and exercises with video resolutions, tailored for weekly study and preparation for exams like Enem.
The text explains the fundamental differences between ionic and covalent bonds, illustrating how an ionic bond involves electron transfer between a metal and a nonmetal, while a covalent bond entails electron sharing between nonmetals or a nonmetal and hydrogen, with variations like single, double, and triple bonds, as well as the unique concept of a dative covalent bond for achieving stability through electron pair sharing.

A complete chemistry platform is available with organized content for weekly study, including videos, PDF materials, objective and discursive questions, mind maps, and exercises with video resolutions.
Each exercise on the platform includes a video resolution showcasing techniques for quick problem-solving, particularly for Enem exams.
The platform offers model simulations, monitoring, and more to aid in studying chemistry efficiently.
The platform also includes an e-book called "Chemistry Rapidex" with 91 pages covering recurring themes from recent Enem editions, including theory, quick problem-solving tricks, and video solutions.
The e-book allows for easy access through scanning a QR code with a cell phone.
The ionic bond involves the transfer of electrons from a metal to a nonmetal, exemplified by sodium chloride (NaCl).
Sodium, a metal, loses an electron to chlorine, a nonmetal, resulting in an attraction between ions of opposite charges, forming an ionic bond.
In contrast, a covalent bond involves the sharing of electrons between nonmetals or a nonmetal and hydrogen, ensuring both parties benefit.
Different types of covalent bonds exist, such as single, double, and triple bonds, exemplified by molecules like O2 and N2.
The dative covalent bond occurs when an atom shares more connections than needed, leading to the sharing of electron pairs to achieve stability, distinct from simple covalent bonds.
