It is [Kr] 4d2 5s2
The correct noble gas configuration for Li is neon (1s^2 2s^1).
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
The noble gas that has the same electron configuration as the oxygen atom in a water molecule is neon (Ne). Both have a full valence shell with 8 electrons, making them stable and unreactive.
Zirconium tetrachloride is obtained by the chlorination of zirconium dioxide (not zirconium carbide).
An atom with 8 electrons in its outer shell is stable and is considered to have a full valence shell. This configuration is known as the octet rule, which means the atom is unlikely to form chemical bonds with other atoms as it is already in a stable state.
The symbol for the noble gas used to represent the core electrons of zirconium is [Kr] (krypton). This notation indicates that the core electrons of zirconium are equivalent to the electron configuration of krypton, which is a noble gas with a filled electron shell, so Zr would have the same core electron configuration as Kr.
The electron configuration of zirconium is: [Kr]5s24d2
The electron configuration of americium is [Rn]5f7.7s2.
[Xe] 4f3 6s2
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
[Kr] 5s2 4d2
The correct noble gas configuration for Li is neon (1s^2 2s^1).
[Xe] 4f3 6s2
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
If you think to the electron configuration of promethium this begin with [Xe].
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
The noble gas configuration for zirconium (Zr - atomic weight 40) is based on krypton: [Kr] 4d2 5s2 The full electronic configuration is : 1s2 2s2 2p6 3s2 3p6 3d104s2 4p6 4d2 5s2
