The amount of energy required to separate 1 mole of ions in a crystalline solid into separate gaseous ions is called energy. This energy provides a measure of the strength of a(n) bond, since the stronger the bond, the the amount of energy required to break it.

A) Are you asking for the production of "ions" from a solid? Or are you asking for the formation of gases. For gases, this is called "energy of vaporization."

B) "Lattice," I am guessing.

C) Greater

Explanation: Most molecules enjoy their existance as solids (not all) due to the intermolecular forces that attract the molecules to each other. These are largely hydrogen and ionic bonds. Hydrophobic compounds don't always share this enthusiam to stick together. Gasoline is happy to leave it's relatives behind and it's Up, Up, and Away.

there is none because earth is stationary and flat.
