AI Generated Solution

To solve the question, "Copper will have ...........work function than sodium," we need to compare the work functions of copper and sodium based on their properties. ### Step-by-Step Solution: 1. **Understanding Work Function**: The work function (ϕ) is the minimum energy required to remove an electron from the surface of a material. A lower work function indicates that it is easier to eject electrons from that material. 2. **Comparing Sodium and Copper**: From chemistry, we know that sodium (Na) is an alkali metal, which has a relatively low ionization energy. This means it is easier to remove an electron from sodium compared to other metals. In contrast, copper (Cu) is a transition metal with a higher ionization energy. ...
