Question

Answer the following for chromium:

Using the spdf form, write out the expected electron configuration for chromium.
The actual electron configuration is 1s²2s²2p⁶3s²3p⁶3d⁵4s¹, how does the expected differ from the actual?
How can we be certain that the actual is chromium and not potassium, which also ends with 4s¹ in its electron configuration?
How many valence electrons does chromium have?
Based on these findings, what other elements, by symbol, will have actual electron configurations that differ from the expected.
