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.
The orbital notation for thallium is [Xe}4f14.5d10.6s2.6p1.
Rubidium has one valence electron in the 5s orbital.

An unoccupied orbital is represented by an empty box in orbital notation. It does not have any electrons present in it but is available to accept electrons if needed.
The orbital notation for vanadium is 1s2 2s2 2p6 3s2 3p6 4s2 3d3.
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.
The element with this orbital notation is nickel (Ni), a transition metal.
The 5s orbital has a lower energy level than the 4d or 4f orbitals in a rubidium atom, according to the aufbau principle. Electrons fill orbitals starting from the lowest energy level to the highest energy level. This is why the electron fills the 5s orbital before the 4d or 4f orbitals in a rubidium atom.
The orbital notation for oxygen is 1s^2 2s^2 2p^4. This indicates that oxygen has two electrons in the 1s orbital, two electrons in the 2s orbital, and four electrons in the 2p orbital.
[Rn]7s2
The orbital notation for beryllium (Be) is 1s^2 2s^2. This notation represents the distribution of electrons in the beryllium atom's electron shells and subshells.
Electronic configuration of boron: [He]2s2.2p1.
