If the electron configuration of a element is p1s2 2s2 2P5, how many unpaired electron are there?
Maelezo ya Majibu
The electron configuration of an element provides information about the arrangement of electrons in its orbitals. In this case, the element has 1 electron in the 2p sublevel, which means it has one unpaired electron. The remaining 7 electrons are paired up in the other orbitals (2 electrons in the 2s sublevel and 4 electrons in the 2p sublevel). Therefore, the answer is (C) 1 unpaired electron.
