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 Li and Na have ns1 in common which comes at last of their electronic configuration as they belong to IA subgroup.
The outer shell contains 1 electron, ns1 Li [He] 2s1 K [Ar]4s1
[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 Li and Na have ns1 in common which comes at last of their electronic configuration as they belong to IA subgroup.
2
The outer shell contains 1 electron, ns1 Li [He] 2s1 K [Ar]4s1
The negative ion F has the same electronic configuration as the positive ion Li?
[He] 2s1
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 electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
+!. The lakali metals are Li, Na K etc in group 1 with an electronic configuration with just ns1 as the outer shell.
[He] 2s1
