Complete the following statement: An individual copper atom emits electromagnetic radiation with wavelengths that are

Options

A. Evenly spaced across the spectrum
B. Unique to that particular copper atom
C. The same as other elements in the same column of the periodic table
D. Unique to all copper atoms

Answer

To complete the statement "An individual copper atom emits electromagnetic radiation with wavelengths that are...", we need to consider the unique properties of copper as an element and the nature of atomic emission spectra.

### Step-by-Step Solution:

1. **Understanding Atomic Emission**:
- Every element, including copper, has a unique emission spectrum. This spectrum is determined by the energy levels of the electrons in the atom. When an electron in a copper atom absorbs energy, it can move to a higher energy level (excitation). When it returns to its original level, it emits energy in the form of electromagnetic radiation.

**Hint**: Remember that the emission spectrum is unique for each element due to its specific electron configuration.

2. **Identifying Wavelengths**:
- The wavelengths of the emitted radiation correspond to the differences in energy levels. The energy difference between these levels determines the wavelength of the emitted light. For copper, these wavelengths are not evenly spaced; they depend on the specific energy transitions of the electrons.

**Hint**: Think about how energy levels in an atom are quantized and how this affects the emitted wavelengths.

3. **Collective Nature of Emission**:
- While each individual copper atom emits radiation at specific wavelengths, all copper atoms will emit the same wavelengths because they all have the same electronic structure. Thus, the emission spectrum is unique to copper as an element, not to individual atoms.

**Hint**: Consider how the properties of an element are consistent across all its atoms.

4. **Final Statement**:
- Therefore, we can complete the statement as follows: "An individual copper atom emits electromagnetic radiation with wavelengths that are unique to copper as an element."

**Hint**: Focus on the uniqueness of the emission spectrum for the element rather than for individual atoms.

### Final Answer:
"An individual copper atom emits electromagnetic radiation with wavelengths that are unique to copper as an element."
