IONIC BONDING

1. IONIC BONDING by: LEVIE L NAGARIT

2. Chemical Bond   is the general term used to  describe the forces that hold atoms together in molecules and ions . https ://chem.libretexts.org

3. Why do atoms undergo chemical bonding? a toms are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons). h ttps://www.google.com/search?q=Why+do+elements+undergo+chemical+bonding%3F&sourc e

4. Octet Rule T he tendency of atoms to have eight electrons in the valence shell h ttps://www.google.com/search?q=Why+do+elements+undergo+chemical+bonding%3F&sourc e

5. How to achieve the octet rule? The atoms combine to attain a noble or inert gas electronic configuration, in order to complete their octet by formation of a chemical bond either by sharing, losing or gaining electrons. h ttps://www.google.com/search?q=Why+do+elements+undergo+chemical+bonding%3F&sourc e

9. Ionic bond the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation , whereas the nonmetal accepts those electrons to become a negatively charged anion.

17. Characteristics of Ionic Bond https://tutors.com/lesson/ionic-compounds-definition-properties-examples Other physical properties of ionic compounds: High melting points and high boiling points They are generally hard and brittle They are electrically neutral They form efficient insulators (ionic solid) They conduct electricity when dissolved in water High enthalpies of fusion (thermal energy needed to melt one mole of the solid form) and vaporization (thermal energy needed to vaporize one mole of the liquid form)
