WebThe electron configuration for lithium uses only the 1s and 2s subshells. The third electron in lithium has to go into the second level because the 1s is completely filled after two electrons occupy the level. You try doing the … WebThis need to gain a filled valance electron shell by having 8 valence electrons is known as the octet rule and explains why certain elements are stable or unstable despite being electrically neutral. This octet rule holds for elements in the second and third periods (or rows) of the periodic table.

Webeight electrons occupy the second shell one electron occupies the third shell This electronic structure can be written as 2,8,1 (each comma, or dot, separates one shell from the next). WebSep 5, 2024 · Both electrons fit into the 1s subshell because s subshells can hold up to 2 electrons; therefore, the electron configuration for helium atoms is 1s 2 (spoken as “one-ess-two”). The 1 s subshell cannot hold 3 electrons (because an s subshell can hold a maximum of 2 electrons), so the electron configuration for a lithium atom cannot be 1 s 3 .
