Question

write electronic configuration of cr ,cu,​

Answer 1

Answer:

In writing the electron configuration for Chromium the first two electrons will go in the 1s orbital. ... After the 4s is full we put the remaining four electrons in the 3d orbital and end with 3d4. Therefore the expected electron configuration for Chromium will be 1s22s22p63s23p44s23d9
