To determine the name of the element from its electron configuration, follow these steps:

1. Identify the given electron configuration:
[tex]\[ 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^{10} 5p^5 \][/tex]

2. Count the total number of electrons in the configuration:
- [tex]\(1s^2\)[/tex]: 2 electrons
- [tex]\(2s^2\)[/tex]: 2 electrons
- [tex]\(2p^6\)[/tex]: 6 electrons
- [tex]\(3s^2\)[/tex]: 2 electrons
- [tex]\(3p^6\)[/tex]: 6 electrons
- [tex]\(4s^2\)[/tex]: 2 electrons
- [tex]\(3d^{10}\)[/tex]: 10 electrons
- [tex]\(4p^6\)[/tex]: 6 electrons
- [tex]\(5s^2\)[/tex]: 2 electrons
- [tex]\(4d^{10}\)[/tex]: 10 electrons
- [tex]\(5p^5\)[/tex]: 5 electrons

3. Add up all the electrons:
[tex]\(2 + 2 + 6 + 2 + 6 + 2 + 10 + 6 + 2 + 10 + 5 = 35\)[/tex]

4. Determine the atomic number:
- The total number of electrons in a neutral atom equals the atomic number. Therefore, the atomic number of the element is 35.

5. Identify the element with atomic number 35:
- The element with atomic number 35 is Bromine (Br).

Thus, the element with the given electron configuration is Bromine.
