Two … WebWhen the carbon atom is excited, then the carbon atom absorbs energy. As a result, an electron in the 2s orbital jumps to the 2p z orbital. Therefore, the electron configuration of carbon (C*) in an excited state will be 1s 2 2s 1 2p x1 2p y1 2p z1. Here, carbon has four unpaired electrons.

WebThere is no p subshell in shell number 1, so that is part of why the lightest elements do not follow the octet rule (there are other reasons). There are many considerations as to what … WebThe atomic number of lithium is 3. That is, the number of electrons in lithium is 3. Therefore, a lithium atom will have two electrons in the first shell and one in the 2nd shell. Therefore, the order of the number of electrons in each shell of the lithium(Li) atom is 2, 1. Electrons can be arranged correctly through orbits from elements 1 to 18.

WebThe electrons in an atom are arranged in shells that surround the nucleus, with each successive shell being farther from the nucleus. Electron shells consist of one or more subshells, and subshells consist of one or more atomic orbitals.
