How many protons does rubidium 85 have?
Similarly one may ask, how many protons neutrons and electrons does rubidium 87 contain?
An electron has very little mass by comparison, protons have a positive charge, electrons have a negative charge, and neutrons-none. The nucleus of 87Rb contains 37 protons(p) and 50 neutrons(n).
Beside above, what is the atomic mass of rubidium 85? Rubidium has two naturally occurring isotopes, Rubidium-85 (relative mass 84.9118 amu) and Rubidium-87 (relative mass 86.9092 amu). If rubidium has an average atomic mass of 85.47 amu, what is the abundance of each isotope (in percent, %)? Be sure to report the correct number of significant figures. 3.
