Why do ionic compounds have relatively high melting points?
There are weak Coulombic attractions between the ions.
There are strong Coulombic attractions between ions.
The atoms share electrons which holds them far apart.
The coulombic attraction between ions keeps them far apart.
The ionic compound sodium bromide melts at 747 degrees Celsius. If a scientists wanted to conduct experiments about how it conducts electricity, what could the scientist do?
The scientist could use a hammer to break any crystals into smaller pieces to study.
The scientist could dissolve some of the compound in water
The scientist could just test the solid compound as it is.
The scientist could heat the compound up to above 747 degrees Celsius and it should conduct electricity.

The melting point of perovskite is 1980°C because the Coulombic attraction between atoms holds them closely together.
The melting point of perovskite is 1980°C because the sharing of electrons between atoms holds them closely together.
The melting point of perovskite is 1980°C because the sharing of electrons between atoms holds them far away from each other.
