Both lithium (Li) and sodium (Na) have one electron in their outermost energy level, giving them similar electronic configurations. They both have an electron configuration of [Ne] 3s¹, where [Ne] represents the electron configuration of the noble gas neon.
Li, Be, O: the first term in the abridged electron configuration is [He]. Ca, K: the first term in the abridged electron configuration is [Ar].
Mg2+: [1s22s22p6]
The negative ion F has the same electronic configuration as the positive ion Ne. This is because the negative ion F gains an electron to achieve a stable octet configuration, similar to the stable electronic configuration of the noble gas Ne.

the electron dot structure for lithium is Li ' (the element symbol with one dot on the upper right side)
what is the electronic configuration of the atomC6
The electronic configuration of tin is: [Kr]D10.5s2.5p2.
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
Both lithium and potassium have one electron in their outermost energy level (Li: 2-1, K: 2-8-8-1). This similarity in electronic configuration gives them similar chemical properties, particularly in terms of reactivity and the ability to form positive ions by losing their outermost electron.
