Question

ionic compound properties

Answer 1

✌✌ Hiii mate here is your answer✌✌


They form crystals.

...They have higher enthalpies of fusion and vaporization than molecular compounds.

They are hard.They are brittle

.They have high melting points and also high boiling points.

They conduct electricity but only when they are dissolved in water.

Hard.

Form crystal lattices not molecules.

Good insulators.

High melting points/ Boiling Points.

Conduct electricity when dissolved in water or as a liquid.

Solids do not conduct electricity.


✌✌hope it's helpful for you✌✌

Answer 2

Answer:

properties of ionic compounds:-)

1. Physical state -

ionic compounds are crystalline solids so they exist in FCC, BCC, hCP arrangement.

ex*-NaCl exist in FCC arrangement and its coordination number is 6.

2. Melting and Boiling point-

they have by melting and boiling point due to close packing in particles.

3. solubility-

ionic compounds are soluble in water due to high hydration than lattice enthalpy.

4. conductivity-

ionic compound can conduct electricity and heat in molten or Aqua state due to presence of free ions.

5. non directional nature-

ionic bonds are nondirectional because a positive charge iron attract each other by any direction.
