Question

write the Electronic configuration of calcium and chromium ?​

Answer 1

Answer:

In writing the electron configuration for Chromium the first two electrons will go in the 1s orbital. ... Therefore the expected electron configuration for Chromium will be 1s22s22p63s23p44s23d9. Note that when writing the electron configuration for an atom like Cr, the 3d is usually written before the 4s.

Answer 2

In writing the electron configuration for Chromium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Chromium go in the 2s orbital. The next six electrons will go in the 2p orbital.
