Ionic Bonds

Question 1

ionic bonds

Answer 1

form between atoms that have significantly different electronegativities
metal + non metal

Question 2

why do ionic bonds tend to form between metals and non metals

Answer 2

metals lose electrons because they have low ionization energies, while nonmetals gain electrons because they have high electron affinities. These processes are complementary, leading to the formation of an ionic bond.

Question 3

5 characteristics of ionic compounds

Answer 3

• high melting & boiling point due to electrostatic interactions
• solubility of ions in water due to interactions with polar solvents
• good conductors of heat and electricity
• crystal lattice rearrangement to minimize repulsive forces
• large electronegativity differences between ions
