[Kr] 4d7 5s1
[Kr] 5s1
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
Rubidium has an atomic number of 37, making it an alkali metal. This means that its last shell is an s with only one electron. The full notation is [Kr] 5s1.
Yes, it is acceptable to use the noble gas configuration to represent the electron configuration of some elements. This simplifies the process by labeling the core electrons as the nearest noble gas configuration and then adding the valence electrons for the specific element.
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 noble gas core for fluorine is neon. So the electron configuration for fluorine with a noble gas core is [Ne] 3s^2 3p^5.
Definition: A noble gas core is an abbreviation in an atom's electron configuration where the previous noble gas's electron configuration is replaced with the noble gas's element symbol in brackets. ... This is the noble gas core notation of sodium.

The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
[Kr]5s1 would be the noble gas electron configuration for Rb.
