To determine the electronic configuration of an element with 47 electrons, we can follow the Aufbau principle, which states that electrons fill the atomic orbitals in order of increasing energy.
The electronic configuration of an element with 47 electrons can be represented as follows:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p³
Breaking it down:
- The first shell (1s) can hold 2 electrons (1s²).
- The second shell (2s and 2p) can hold 8 electrons (2s² 2p⁶).
- The third shell (3s and 3p) can hold 8 electrons (3s² 3p⁶).
- The fourth shell (4s, 3d, and 4p) can hold 18 electrons (4s² 3d¹⁰ 4p⁶).
- The fifth shell (5s, 4d, and 5p) can hold 18 electrons (5s² 4d¹⁰ 5p⁶).
- The sixth shell (6s, 4f, 5d, and 6p) can hold 32 electrons (6s² 4f¹⁴ 5d¹⁰ 6p³).
Thus, the electronic configuration of an element with 47 electrons is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p³.
