Rhenium falls within the transition metal category. Let us study the electron configuration of rhenium below.

**Rhenium has the electron configuration of 1s ^{2 }2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2 }3d^{10 }4p^{6} 5s^{2 }4d^{10 }5p^{6 }4f^{14 }6s^{2 }5d^{5}. Elements like Rhenium chlorides, and ReCl_{6}, have chemical behaviour that is explained by their electronic configuration. The melting and boiling temperatures are 3186°C and 5630°C, respectively. **

Let us talk about Rhenium’s interesting facts like the electron configuration diagram, distribution of electrons and electron configuration in this article.

**How to write Rhenium electron configuration?**

**Rhenium has an atomic number of 75. The electrons are organised in the Rhenium atom through the following list:**

**Step 1**:**First of all count the electron shell****There are six electron shells in the Rhenium altogether. There are 2, 8, 18, 32, 13, and 2 electrons in each of these six shells.****Step 2: Symbolize the orbit****The orbitals with the symbols s, p, d, and f can accommodate electron arrangements. These are denoted by the numerals 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 5s and so on.****After symbolizing the orbital determine how the orbitals are ordered by energy according to the Aufbau principle.****Re**energy order : 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p.**Step 3:****The orbitals are filled with electrons**,**According to Pauli’s exclusion principle.****Only two electrons with different spins can coexist in each orbital.****Step 4: Electrons are then arranged in orbitals according to the overall electron configuration that should be expressed in superscripts when using the orbital ordering notation.****According to Hund’s rule, all orbitals of the sub-shell or energy level must be occupied before electron pairing.****The electron configuration that results is 1s**^{2 }2s^{2}2p^{6}3s^{2}3p^{6}4s^{2 }3d^{10 }4p^{6}5s^{2 }4d^{10 }5p^{6 }4f^{14 }6s^{2 }5d^{5}.
