# The binding energy data for the occupied subshells of gaseous carbon atoms obtained from photoelectron spectroscopy are shown in the table below.

| Subshell | Binding Energy (\(10^{-18}\text{ J}\)) |
| :—: | :—: |
| \(1s\) | \(47.5\) |
| \(2s\) | \(3.5\) |
| \(2p\) | \(1.5\) |

A sample of gaseous carbon atoms is irradiated with radiation where each photon has an energy of \(6.0 \times 10^{-18}\text{ J}\). What is the kinetic energy of an electron ejected from the \(2p\) subshell?

The binding energy data for the occupied subshells of gaseous carbon atoms obtained from photoelectron spectroscopy are shown in the table below.

| Subshell | Binding Energy (\(10^{-18}\text{ J}\)) |
| :---: | :---: |
| \(1s\) | \(47.5\) |
| \(2s\) | \(3.5\) |
| \(2p\) | \(1.5\) |

A sample of gaseous carbon atoms is irradiated with radiation where each photon has an energy of \(6.0 \times 10^{-18}\text{ J}\). What is the kinetic energy of an electron ejected from the \(2p\) subshell?

- **A.** \(1.5 \times 10^{-18}\text{ J}\)
- **B.** \(2.0 \times 10^{-18}\text{ J}\)
- **C.** \(2.5 \times 10^{-18}\text{ J}\)
- **D.** \(4.5 \times 10^{-18}\text{ J}\)
