The FeNH3^6^2^+ complex ion has six ammonia ligands, each contributing one lone pair of electrons to form a coordinate bond with the iron (Fe) ion. Since iron has a +2 charge, and each ammonia ligand donates one electron pair, there will be a total of four unpaired electrons on the iron atom.
Antimony (Sb) has an atomic number of 51, and its electron configuration is [Kr] 5s² 4d¹⁰ 5p³. In the Sb³⁺ oxidation state, it loses three electrons, typically from the 5p and 5s orbitals, resulting in the configuration [Kr] 4d¹⁰. Consequently, Sb³⁺ has no unpaired electrons, as all its electrons are paired in the filled 4d subshell.
Tungsten generally loses electrons when forming bonds, it is a metal
Lets look at a water molecule, H2O. The central atom is the larger oxygen atom, which has 6 electrons in its outer shell (and is therefore in the 6A column of the periodic chart). They divide into 4 orbitals, so 2 orbitals will have 2 electrons, and 2 will have just one. Those unpaired electrons share the electron of a hydrogen atom to form a water molecule. All of the electron pairs (whether shared or not) are negatively charged, and since like charges repulse, they are all trying to repulse each other. But the unshared electron pairs are a little stronger (they don't have a positively-charged hydrogen atom lurking around), and so they actuall shove the hydrogen atoms closer together than they would like to be, Just from the geolmetry, we'd expect the hydrogen bonds to be separated by an angle of 109 degrees, but the strong unshared electron pairs push them toward each other so that their angle is 105 degrees.
Magnesium has 2 electrons in its outermost electron shell. As a result, you would expect magnesium to form ions with a charge of +2 by losing these two outer electrons to achieve a stable electron configuration.
All electrons in every atom are located around the nucleus. In carbon atoms there are two electrons in the first principal energy level and four in the second.
You wouldn't expect strontium to gain electrons in a chemical change.

The cohesin complex will be destroyed, and the cell will remain in metaphase.

If your apartment complex or neighborhood has lots of great amenities, don't expect them to be free.
I would expect the metals potassium, barium, and copper to lose electrons during chemical reactions. I would expect the nonmetals fluorine and sulfur to gain or share electrons depending of the chemical reaction.
