The atomic number of rubidium is 37. if the mass number of rubidium is 85 how many subatomic particles are found inside and outside of the nucleus of the rubidium atom? Number of particles inside Nucleus Number of particles outside Nucleus

85 inside,37 outside

Explanation:

85 inside =37 protons and 48 neutrons

37 outside=37 electrons

Hope this helps

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
