Определите, атомы каких их предложенных элементов имеют в возбуждённом состоянии электронную конфигурацию внешнего энергетического уровня .

1) O

2) S

3) C

4) Te

5) Si

The electron configurations of the elements in their excited state can be determined by looking at the atomic number and the given energy level diagram.

1. O (Oxygen) - The atomic number of oxygen is 8. From the energy level diagram, we can see that the outermost energy level contains 6 electrons. Thus, in the excited state, the electron configuration would be 2s2 2p4.

2. S (Sulfur) - The atomic number of sulfur is 16. From the energy level diagram, we can see that the outermost energy level contains 6 electrons. Thus, in the excited state, the electron configuration would be 3s2 3p4.

3. C (Carbon) - The atomic number of carbon is 6. From the energy level diagram, we can see that the outermost energy level contains 4 electrons. Thus, in the excited state, the electron configuration would be 2s2 2p2.

4. Te (Tellurium) - The atomic number of tellurium is 52. From the energy level diagram, we can see that the outermost energy level contains 6 electrons. Thus, in the excited state, the electron configuration would be 5s2 5p4.

5. Si (Silicon) - The atomic number of silicon is 14. From the energy level diagram, we can see that the outermost energy level contains 4 electrons. Thus, in the excited state, the electron configuration would be 3s2 3p2.
