An oxygen atom has 8 electrons, and thus 6 valence electrons. 4 of these are paired, giving us 2 unpaired lectrons. This also means oxygen can connect to 2 other atoms through a basic bond, or 1 atom through a double bond.
An atom of antimony in its ground state has 3 unpaired electrons.
Iodine has one unpaired electron in its ground state.
3 electrons. This can be told from the periodic table. These electrons are in the 2p orbital.
Magnesium has five unpaired electrons and is therefor paramagnetic
Boron (B), Aluminum (Al), and Bromine (Br) each have 1 unpaired electron in the ground state. Oxygen (O) does not have any unpaired electrons in its ground state configuration.
Phosphorus has three unpaired electrons in its ground state.
An atom of antimony in its ground state has 3 unpaired electrons.
Iodine has one unpaired electron in its ground state.
3 electrons. This can be told from the periodic table. These electrons are in the 2p orbital.
There are 5 unpaired electrons in Fe^3+ in its ground state.
Magnesium has five unpaired electrons and is therefor paramagnetic
Boron (B), Aluminum (Al), and Bromine (Br) each have 1 unpaired electron in the ground state. Oxygen (O) does not have any unpaired electrons in its ground state configuration.
Noble gases, like helium, neon, and argon, have no unpaired electrons in their ground state electron configuration. This means that all of their electrons are paired up in orbitals.
Hund's Rule
There are 5 unpaired electrons in Fe^3+ in its ground state.
Germanium has 0 unpaired electrons in its ground state, as it has a completely filled 4s and 4p orbitals, resulting in a full outer shell configuration.
