what is the electron configuration of vanadium?
23V = 1s2 2s2 2p6 3s2 3p6 3d3 4s2
To determine the electron configuration of an element such as vanadium (V), you need to follow a specific order in which the electron shells and subshells fill up.
1. Start by determining the atomic number of vanadium. Vanadium has an atomic number of 23, which means it has 23 electrons.
2. Now, proceed to fill in the electron configuration using the Aufbau principle. This principle states that electrons fill the lowest energy levels first before moving to higher levels.
The electron configuration of vanadium (V) is: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³
Explanation:
- The 1s subshell can hold a maximum of 2 electrons (1s²).
- The 2s subshell can hold a maximum of 2 electrons (2s²).
- The 2p subshell can hold a maximum of 6 electrons (2p⁶).
- The 3s subshell can hold a maximum of 2 electrons (3s²).
- The 3p subshell can hold a maximum of 6 electrons (3p⁶).
- The 4s subshell can hold a maximum of 2 electrons (4s²).
- Finally, the 3d subshell can hold a maximum of 10 electrons, but in the case of vanadium, we have 3 electrons occupying it (3d³).
Thus, the electron configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.
