Radium (Ra) has an atomic number of 88, which means it has 88 electrons. Its electron configuration is [Rn] 7s², indicating that the 7s subshell is fully filled with two electrons, leaving no unpaired electrons. Therefore, radium has zero unpaired electrons in its ground state.
There are no unpaired electrons in strontium.
Nickel has two unpaired electrons.
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
The neutral radium atom has 88 electrons, the radium cation has 86 electrons.
Radium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, radium has 2 valence electrons.
There are no unpaired electrons in strontium.
three unpaired electrons
Aluminum has three unpaired electrons.
Germanium has 4 unpaired electrons.
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
6 unpaired electrons
Phosphorus has three unpaired electrons in its ground state.
Nickel has two unpaired electrons.
Xenon has eight unpaired electrons.
Neodymium (Nd) has 3 unpaired electrons.
Titanium (Ti) has four unpaired electrons.
Phosphorus has 3 unpaired electrons in its outermost shell.
