Text Solution

AI Generated Solution

To determine the outermost electron configuration of chromium (Cr), we can follow these steps: ### Step 1: Identify the Atomic Number The atomic number of chromium (Cr) is 24. This means that a neutral chromium atom has 24 electrons. **Hint:** The atomic number of an element indicates the number of protons and, in a neutral atom, also the number of electrons. ### Step 2: Write the Electron Configuration ...
