Rubidium has one 5s electron.
Oxygen as 2 core electrons and 6 valence electrons.
4 Ground state configuration is 5s^1 4^4
Technetium has 43 protons and electrons.
2. The elctron configuratio of Cd is [Kr] 4d10 5s2
Rubidium has one 5s electron.
5s orbital
Rubidium has one valence electron in the 5s orbital.
Oxygen as 2 core electrons and 6 valence electrons.

If you are filling in the electrons it will be in the 4d orbital. If you are removing electrons the first to come out is in the 5s electrons since transition metals lose 's' electrons before 'd' electrons
Valance electrons are furthest from the nucleus.
