Elements: U and Li

Compounds:
`H_2O`,
`MgCl_2`, and
`Li(OH)_2`

Step-by-step explanation:

Elements are pure substances that are not bonded with any other atom. They are found in the Periodic Table of Elements. For this question, only U and Li are pure substances, they are the only items listed in the Periodic Table, and they are the only elements in the list.

Compounds are groups of elements that are chemically bonded. When writing them, the elements that compose them are listed.
`H_2O` is two hydrogen and one water,
`MgCl_2` is one magnesium and two chlorine, and
`Li(OH)_2` is one lithium and two hydroxide ions. The two hydroxide ions are composed of one hydrogen and one oxygen each. These three items are all compounds of various elements.
