Astudent is working with four different solid substances: sodium (na), calcium (ca), copper (cu), and iodine (i). which substance is most likely to break easily into many smaller pieces? sodium calcium copper iodine

The correct option is IODINE.

Iodine is a non metal and it exist as a solid at room temperature. It has a glistering crystalline appearance. Iodine is a molecular solid and each molecule is made up of two atoms that are linked together by covalent bond and each iodine molecule is bonded to the next by weak vander waals forces. Thus, iodine has low melting and boiling points. These properties make iodine to have the tendency of breaking easily.

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
