Two isotopes of the element rubidium differ in their number of protons?
This statement is incorrect. Isotopes of an element have the same number of protons but differ in their number of neutrons. Rubidium, specifically, has two stable isotopes: Rb-85 and Rb-87, which both have 37 protons but different numbers of neutrons.
What is the atomic number in rubidium?
The atomic number of rubidium is 37.
How long is Rubidium's half life?
Most rubidium (about 72.2%) is of the isotope 85Rb, which is stable. The remainder of natural rubidium (about 27.8%) is of isotope 87Rb, which has a half life of 4.88 x 1010 years and decays into 87Sr. There are a number of other isotopes of Rubidium, all of which are synthetic, having half lives ranging from less than a microsecond to something more than 86 days.
