electrostatic attraction sharing of electrons close together far away from each other
the melting point of perovskite is 1980°c because the between atoms holds them.

Explanation:

Perovskite is an ionic compound. Ionic compounds have high melting points because of the strong electrostatic attraction between ions (which are atoms in this context as we are talking about the forces between atoms in the compound structure). This strong electrostatic attraction holds the atoms close together, requiring a lot of energy (high temperature) to break the bonds and melt the compound. Sharing of electrons is characteristic of covalent bonds (which would have different melting - point trends, usually lower for simple covalent molecules). Atoms being far away from each other would imply weak forces and a low melting point.

Answer:

The first blank: electrostatic attraction; The second blank: close together
