Rubidium has one 5s electron.
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
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.
Ruthenium has an atomic number of 44, which means it has 44 protons and, in a neutral atom, 44 electrons. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. Therefore, there are 44 electrons in a neutral atom of ruthenium.
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.
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
Rubidium has one valence electron in the 5s orbital.
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.

This alkali metal is Rubidium Rb, having atomic no 37
The orbital diagram for Rb (Rubidium) is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1. This represents the distribution of electrons in the different energy levels and sublevels of the Rubidium 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.
[Kr] 5s1
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.
Ruthenium has an atomic number of 44, which means it has 44 protons and, in a neutral atom, 44 electrons. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. Therefore, there are 44 electrons in a neutral atom of ruthenium.
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.
