37.
Each atom of Rubidium (Rb) has 37 protons.
There are 37 protons in one atom of rubidium-85.
protons-37neutrons-48electrons-37
Its atomic # is 37 so 37 protrons and electrons as for nuetrons it is 85(atomicmass)- 37(the atomic number)=48
Rubidium has 37 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a rubidium isotope = Mass number - 37
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.
the atomic number of any element is the number of protons in its nucleus, so in this case, 31, Gallium
The element rubidium (Rb) as a single atom has thirty-seven protons.
Rubidium has 37 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a rubidium isotope = Mass number - 37
The atomic number of rubidium is 37. That means it has 37 protons and 37 electrons. After we fill in the first 37 orbitals with electrons, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Since 5 is the highest numbered shell, rubidium has 1 valence electron.
Rubidium.
A rubidium atom has 37 protons, 27 electrons and usually 48 neutrons. Though another fairly common isotope has 50 neutrons.
