WebThe electron configuration and orbital diagram of helium are: The n = 1 shell is completely filled in a helium atom. The next atom is the alkali metal lithium with an atomic number of 3. The first two electrons in lithium fill the 1 s orbital and have the same sets of four quantum numbers as the two electrons in helium. WebIn the case of H2O: The electron configuration shows that an electron exists in the hydrogen atom. Again, the electron configuration of oxygen shows that there are six electrons in the last orbit of the oxygen atom. Two hydrogen atoms join one oxygen atom to form a covalent bond through electron sharing.
