Haley is working with other students, each one doing research on something in the universe. So far, the only thing that Haley knows about her topic is that these objects are
relatively small and that they sometimes have a solid, rocky surface. What is Haley's
research topic?

Ifound this on google “these two compounds have a different ionic structure. caesium ion is larger in size when compared to the sodium ion. the charge gets more area to spread out evenly. so caesium chloride has a lower melting point than sodium chloride.” i hope this you for what your looking for

Of course: ) what’s your name ?
