Answer
Based on this information, the two checks are:1. Copper is harder. (
)2. Copper is less reactive. (
)
Explanation
## Step 1: Identify the Differences:We first need to distinguish the fundamental differences between sodium (an alkali metal) and copper (a transition metal).## Step 2: Understand metal properties:Alkali metals, like sodium, are usually softer, can be cut with a banal object like a knife, immensely reactive aspects traceable to their one electron in their outermost energy level, and exist in low densities.On the other hand, transition metals, like copper, are typically harder, less reactive due to their electron orbital configurations, and possess high melting points.
