protons-37neutrons-48electrons-37
There are 37 protons in one atom of rubidium-85.
A rubidium atom has 37 protons, 27 electrons and usually 48 neutrons. Though another fairly common isotope has 50 neutrons.
whatever the number of the element on the periodic table is
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Rubidium has one valence electron as it an alkali metal.
Each atom of Rubidium (Rb) has 37 protons.
37.
There are 37 protons in one atom of rubidium-85.
Its atomic # is 37 so 37 protrons and electrons as for nuetrons it is 85(atomicmass)- 37(the atomic number)=48
Polonium has 84 protons.
Curium has 96 protons.
11 protons and 10 electrons
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.
A rubidium atom has 37 protons, 27 electrons and usually 48 neutrons. Though another fairly common isotope has 50 neutrons.
Rubidium's atomic number is 37 and atomic number is the same as the protons (37 protons) Protons equal electrons so there is the same number of protons and electrons (37 electrons). The atomic mass of this element is About 85, and protons and neutrons weigh about 1 so you can subtract 37 from 85 to get and 48 neutrons. 37 protons, 37 electrons and 48 neutrons.
Tantalum has 73 protons and electrons and its isotopes have 108 or 107 neutrons.
