Question

define Ionic bond? describe the mechanism of formation NaCl​

Answer 1

Answer:

When sodium (Na) and chlorine (Cl) are combined, the sodium atoms each lose an electron, forming cations (Na+), and the chlorine atoms each gain an electron to form anions (Cl−). These ions are then attracted to each other in a 1:1 ratio to form sodium chloride (NaCl). Na + Cl → Na+ + Cl− → NaCl.

Answer 2

Answer:

Ionic bond, also called electro-valent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. By losing one electron, sodium atom forms a sodium ion (Na+) and by gaining one electron, the chlorine atom forms a chloride ion (Cl-). ... Due to opposite charges, sodium ion and chloride ions are held together by the electrostatic force of attraction to form sodium chloride, Na+Cl- or NaCl
