There should not be any unpaired valence electrons in a pure sample of Fe2O3: This substance is composed of Fe+3 cations and O-2 anions, in which all of the originally unpaired valence electrons in Fe and O atoms have become paired. Since Fe is a transition element, there may or may not be unpaired non-valence electrons in its inner shells.
fe electronic configuration is
1s2 2s2 2p6 3s2 3p6 4s2 3d6.
so , four electrons in the 3d- subshell are unparied.
this exhibits the paramagnetic nature of fe
Fluorine has 1 unpaired electron
there are 0 unpaired electrons
1
3 unpaired electrons
That would be 0. The ground state of every element except for Hydrogen is 1s2 which has no unpaired electrons. (only valence electrons have the ability to be unpaired). Full configuation of Fe would be: 1s2 2s2 2p6 3s2 3p6 4s2 3d6 WWWWWWWWWRRRRRRROOOOOOONNNNNNGGGGGGG!!!!!!!
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
A fluorine atom in the ground state has 7 valence electrons.
Two. The ground state configuration of Sulfur is [Ne] 3s23p4. According to Hund's rule, the p orbitals must fill up separately first. This results in the first 3 electrons going into separate orbitals, and the fourth then doubles up with the first, leaving the other two p orbitals with unpaired electrons.
3 unpaired electrons
An atom of antimony in its ground state has 3 unpaired electrons.
There are 5 unpaired electrons in Fe^3+ in its ground state.
Not in its ground state.
1 unpaired electron
There are 5 unpaired electrons in Fe^3+ in its ground state.
Magnesium has five unpaired electrons and is therefor paramagnetic
Hund's Rule
0
Two
Add the electrons in accordance with the aufbau principle and then count the unpaired ones.
There are 0 unpaired electrons which would make it diamagnetic
