Question

How many protons, neutrons, and electrons does francium have? (The atomic radius would help too)?

Answer 1

The most stable isotope of Francium , number 87, has a mass of 223. That means that it has 87 protons, 87 electrons and 136 neutrons. There isn't very much of it and it is radioactive, decaying quickly. There are 34 known isotopes, so the number of neutrons and mass can vary widely.

Answer 2

87 protons

136 N

87 electrons

Answer 3

Let me find out hold on

87 protons and nuetrons

and 137 electrons.

Radius:

ionic radius (2- ion): pm

ionic radius (1- ion): pm  

atomic radius: pm  

ionic radius (1+ ion): 194 pm  

ionic radius (2+ ion): pm

ionic radius (3+ ion): pm
