Electron configuration of rubidium is 1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s2,4p6, 5s1
Electrons per shell 2,8,18,8,1
Electron configuration is also represented by [Kr], 5s1.
Atomic No. 37,
It is Group 1 Alkali metals
Period 5
It is an s-block element.
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
The ground state electron configuration for nitrogen is [He]2s2.2p3.
The noble gas core configuration of rubidium is [Kr]5s1. It is derived from the electron configuration of the noble gas krypton ([Kr] = 1s22s22p63s23p63d104s24p6), followed by the valence shell configuration of rubidium (5s1).
The electron configuration of lead is [Xe]4f14.5d10.6s2.6p2.
[Kr] 5s1
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
When rubidium, an alkali metal, group 1, reacts it loses one electron.
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
The ground state electron configuration for nitrogen is [He]2s2.2p3.
The ground state electron configuration of bromine is Ar 4s 3d 4p.
The ground-state electron configuration for the V3 ion is Ar 3d2.
The ground state electron configuration for iron (Fe) is Ar 3d6 4s2.
The ground state electron configuration of iron (Fe) is Ar 3d6 4s2.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
The noble gas core configuration of rubidium is [Kr]5s1. It is derived from the electron configuration of the noble gas krypton ([Kr] = 1s22s22p63s23p63d104s24p6), followed by the valence shell configuration of rubidium (5s1).
The ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
