Let's analyze each electron configuration to identify the respective element.

1. Electron Configuration: [tex]\(1s^2 2s^2 2p^6\)[/tex]
- The electron configuration [tex]\(1s^2 2s^2 2p^6\)[/tex] represents a total of [tex]\(2 + 2 + 6 = 10\)[/tex] electrons.
- The element with 10 electrons is Neon (Ne).

2. Electron Configuration: [tex]\(1s^2 2s^2 2p^6 3s^2 3p^3\)[/tex]
- The electron configuration [tex]\(1s^2 2s^2 2p^6 3s^2 3p^3\)[/tex] represents a total of [tex]\(2 + 2 + 6 + 2 + 3 = 15\)[/tex] electrons.
- The element with 15 electrons is Phosphorus (P).

3. Electron Configuration: [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^1\)[/tex]
- The electron configuration [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^1\)[/tex] represents a total of [tex]\(2 + 2 + 6 + 2 + 6 + 1 = 19\)[/tex] electrons.
- The element with 19 electrons is Potassium (K).

4. Electron Configuration: [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6\)[/tex]
- The electron configuration [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6\)[/tex] represents a total of [tex]\(2 + 2 + 6 + 2 + 6 + 2 + 6 = 26\)[/tex] electrons.
- The element with 26 electrons is Iron (Fe).

5. Electron Configuration: [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^3\)[/tex]
- The electron configuration [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^3\)[/tex] represents a total of [tex]\(2 + 2 + 6 + 2 + 6 + 2 + 10 + 6 + 2 + 3 = 41\)[/tex] electrons.
- The element with 41 electrons is Niobium (Nb).

So, the elements corresponding to each electron configuration are:
1. [tex]\(1s^2 2s^2 2p^6\)[/tex]: Neon (Ne)
2. [tex]\(1s^2 2s^2 2p^6 3s^2 3p^3\)[/tex]: Phosphorus (P)
3. [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^1\)[/tex]: Potassium (K)
4. [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6\)[/tex]: Iron (Fe)
5. [tex]\(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^3\)[/tex]: Niobium (Nb)
