Step 1:I'll solve this step by step using the specified LaTeX formatting guidelines:
Step 2:: Analyze the Electron Configuration
- $$3d^{5}$$: Third shell, d orbital, 5 electrons
Let's break down the given electron configuration:
Step 3:: Count Total Electrons
2 + 2 + 6 + 2 + 6 + 2 + 5 = 25 \text{ electrons}
Let's add up all the electrons:
Step 4:: Determine the Element
An element with 25 electrons corresponds to the atomic number 25, which is Manganese (Mn).
Final Answer
The element with the electron configuration 1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{5} is Manganese (Mn).
