1. Radium has 88 protons. 2. Radium has not... americium !
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass - 88 The most stable and known isotope of radium, 226Ra, has 138 neutrons.
Radium has 86 electrons.
Radium has two valence electrons.
There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.
The neutral radium atom has 88 electrons, the radium cation has 86 electrons.
Radium lose two electrons, the cation is Ra2+.
Radium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, radium has 2 valence electrons.
Radium is a chemical metal element. There are 88 electrons in a single atom.
Two electrons in the outer shell of radium.
