Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.

Rubidium has one valence electron in the 5s orbital.
There is actually 37 Protons in Rb (Rubidium). Also there is the same number of protons as electrons. So 37 for protons and electrons. (: Your welcome little kid.
If you look at a periodic table and go to group one, and than the element with an atomic number of 37 it is Rb. The atomic number is the number of protons and electrons. Rb is Rubidium.
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.

Rubidium has one valence electron in the 5s orbital.
In the Rb atom, the electron configuration is [Kr]5s^1. This means there is 1 electron in the 5s sublevel of the Rb atom.
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
There is actually 37 Protons in Rb (Rubidium). Also there is the same number of protons as electrons. So 37 for protons and electrons. (: Your welcome little kid.
Rubidium (Rb) has 1 valence electron. This is because it is in the first group (group 1) of the periodic table, which means it has 1 electron in its outermost shell.
c. Rb plus. Kr has 36 electrons, the same as Se2-, As3+, Sr2+, and Br-. Rb plus has 35 electrons, which is not isoelectronic with Kr.
paramagnetic
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Each atom of Rubidium (Rb) has 37 protons.
The compound RbCl is ionic because it is formed between a metal (Rb) and a non-metal (Cl). Metal and non-metal combinations typically result in ionic compounds where the metal loses electrons to form cations and the non-metal gains electrons to form anions.
RbBr is an ionic compound. It is formed by the transfer of electrons from rubidium (Rb) to bromine (Br), resulting in the formation of positive and negative ions that are held together by electrostatic attractions.
