What is the noble gas configuration of astatine as?
The ground state electronic configuration of Neutral Astatine atom is [Xe] 4f14 5d10 6s2 6p5. The portion of Astatine configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Xe]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.
What is configuration of potassium?
[Ar] 4s¹Potassium / Electron configuration
How do I find the noble gas configuration?
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3s1.
What element has the valence configuration of 3s²3p⁵?
Possible answer: Chlorine’s electron configuration is [Ne]3s²3p⁵, which has its valence electrons in orbitals of the third energy level.
Why potassium has electron configuration?
Hi, According to octet rule, the outermost shell of an atom can accommodate maximum 8 electrons (except K shell which can accommodate maximum 2 electrons). Hence, the electronic configuration of potassium is 2,8,8,1 and not 2,8,9.

How do you find the energy of an atom of astatine?
An atom of Astatine in the gas phase, for example, gives off energy when it gains an electron to form an ion of Astatine. At + e – → At – – ∆H = Affinity = 270.1 kJ/mol To use electron affinities properly, it is essential to keep track of sign. When an electron is added to a neutral atom, energy is released.
