The outer shell contains 1 electron, ns1
Li [He] 2s1
K [Ar]4s1
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].
K+ and argon have the same electron configuration
They each have 1.
The alkali metal cations are lithium (Li+), sodium (Na+), potassium (K+), rubidium (Rb+), cesium (Cs+), and francium (Fr+). These cations are formed when alkali metals lose their outermost electron to achieve a stable electron configuration.
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.
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].
The electronic configuration of potassium, K, is [Ar]4s^1. When potassium loses one electron to become a K+ ion, the electronic configuration changes to that of argon [Ar].
The electronic configuration of potassium (K) is 1s2 2s2 2p6 3s2 3p6 4s1.
+!. The lakali metals are Li, Na K etc in group 1 with an electronic configuration with just ns1 as the outer shell.
K+ is 18 electrons 1s2 2s2 2p6 3s2 3p6
The electronic configuration of iodine is: [Kr] 4d10 5s2 5p5.
1s2 2s2 2p6 3s2 3p6
No, potassium (K) in its K2+ cation form and calcium (Ca) have different electronic configurations than argon (Ar). Potassium has an electron configuration of [Ar] 4s1 and calcium has an electron configuration of [Ar] 4s2. In contrast, argon has an electron configuration of 1s2 2s2 2p6 3s2 3p6.
The element with the electron configuration 2s1 is lithium (Li). However, there is no element with the electron configuration S2d1 as "S" and "d" are not valid subshells in the electron configuration notation based on the periodic table.
K+ and argon have the same electron configuration
