What element has the electron configuration 4s2 3d7?

First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.

What is complete electron configuration for an atom of cobalt?

The electronic configuration of cobalt is :1s2 2s2 2p6 3s2 3p6 3d7 4s2 This is so because cobalt has an atomic no of 27. So it will have 27 electrons. The 1st shell can accommodate a maximum of 2 electrons, the 2nd shell can accomodate 8. So that makes it 10, 17 to go. Now the 3s and 3p subshells get filled up with 2 and 6 electrons respectively, but after that instead of the 3d subshell, the 4s subshell gets filled up.(This is so because the 4s subshell has a lower energy level than 3d).So that makes it 20 electrons. The remaining 7 proceed into the 3d subshell to make a total of 27.
