Radium has two valence electrons.
Nitrogen has 5 electrons available for covalent bonding. It has 5 electrons in its outer shell, meaning it can form stable covalent bonds by sharing these electrons with other atoms.
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 32 electrons available for bonding in the sulfate ion (SO4^2-). Each oxygen contributes 6 valence electrons, and the sulfur contributes 6 valence electrons, giving a total of 32 electrons.
There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.
Aluminum (Al) has three valence electrons available for bonding. It is located in group 13 of the periodic table, where elements typically have three electrons in their outermost shell. These valence electrons can participate in chemical bonding, allowing aluminum to form various compounds.
