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].
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.
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.
[He] 2s1
the electron dot structure for lithium is Li ' (the element symbol with one dot on the upper right side)
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
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.
2
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.
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.

the electron dot structure for lithium is Li ' (the element symbol with one dot on the upper right side)
Lithium (Li) has the electron configuration 1s2 2s1.
[He]2S1
The correct noble gas configuration for Li is neon (1s^2 2s^1).
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
+!. The lakali metals are Li, Na K etc in group 1 with an electronic configuration with just ns1 as the outer shell.
The configuration of the lithium ion (Li⁺) is 1s². In its neutral state, lithium has the electron configuration of 1s² 2s¹, but when it loses one electron to become Li⁺, it loses the 2s electron, leaving only the 1s electrons.
