Argon is a noble gas and being as its highest energy level is completely filled there are no electrons available for bonding in argon.
Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.
Bromine has 7 valence electrons available for bonding.
Two valence electrons
Lithium have available for bonding one electron.
324
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.
Argon has 18 electrons.
Argon has 18 electrons.
There are 6 2p electrons in argon.
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.
Argon has 8 valence electrons.
Argon has 8 valence electrons.
