The valence of radium is 2+.
Radium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, radium has 2 valence electrons.
Radon has 8 valence electrons (electrons in it's outer shell) so does Ne, Ar, Kr, Xe. Helium is in the same line, but only has 2 valence electrons. Hope that helps! Sarah G.
Two electrons in the outer shell of radium.
Radium has 86 electrons.
Elements in group 2A of the periodic table have two valence electrons. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium.

Radium has 86 electrons.
Radium has seven electron shells; the valence of radium is 2+.
Radium has one valence electron.
Elements in group 2A of the periodic table have two valence electrons. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium.
Radium (Ra) has 20 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding and are not part of the valence shell. In the case of radium, the core electrons would include those in the first three energy levels, up to and including the electron configuration [Xe] 6s1.
Group 2 elements have 2 valence electrons. This is because they are located in group 2 of the periodic table, which corresponds to the number of valence electrons in the group. Examples of group 2 elements include beryllium, magnesium, calcium, strontium, barium, and radium.
