Rubidium has 5 electron shells.
The electron configuration of rubidium is [Kr]5s1.
Magnesium has three electron shells. The electron configuration is 2,8,2
Two electrons in the outer shell of radium.
The neutral radium atom has 88 electrons, the radium cation has 86 electrons.
A bismuth atom has 6 electron shells.
Phosphorus in is 3rd period. So it has 3 electron shells.
Radium has seven electron shells; the valence of radium is 2+.
Radium has one valence electron.
Magnesium has three electron shells. The electron configuration is 2,8,2
Bromine has 4 electron shells.
Polonium has 6 electron shells.
Sodium, i believe has 3 shells.
Two electrons in the outer shell of radium.
The neutral radium atom has 88 electrons, the radium cation has 86 electrons.
A sulfur atom has 3 electron shells.
There are 86 core electrons in radium (Ra), which is the number of electrons in filled inner electron shells. Radial's electron configuration is [Rn] 7s2, where [Rn] represents the electron configuration of radon (Rn) as the previous noble gas element.
Uranium has 92 electrons, which means it has 7 electron shells.
The correct number of electron clouds or shells sodium has is 3.
