How do ionic bonds affect the properties of ionic compounds?

the bonds weakly hold ions together, increasing the melting point.
the bonds strongly hold ions together, reducing the boiling point.
the bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.
the bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a poor conductor.

The correct answer is :

The bond prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.

The explanation:

1- the bonds prevent electrons from moving, since the ions are locked in place and don't want their electrons to go.

2- Ionic substances form giant ionic lattices containing oppositely charged ions.

3- They have high melting and boiling points

4- conduct electricity when melted or dissolved in water.

43.452

step-by-step explanation:

284 times .153 = 43.452

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
