Cul (s) --> represents its state which means solid, Here Valency of copper is 1 so its cuprous.
<span>Fe2O3--> Ferric Oxide is a solid. Here valency of Fe is +3 so its Ferric </span>
<span>CoF2--> Cobalt Flouride is a solid</span>
<span>FeO --> Ferrous Oxide is a solid. Here valency of iron is +2 so its Ferrous. </span>
In ionic bonds, one atom gives one or more electrons to another atom so both can get closer to 8 valence electrons. Example: In potassium chloride (KCl), Potassium gives up one valence electron to chlorine, so that the outer shell of potassium has 8 valence electrons. This happens only between metals and nonmetals.
In covalent bonds, atoms share their electrons to reach 8 valence electrons. Example: In water (H2O), Oxygen shares one valence electron with one atom of hydrogen, and another valence electron with another atom of hydrogen. Oxygen now has 8 (4 unshared + 2 of its own + 1 from hydrogen + 1 from hydrogen), and each hydrogen has 2 valence electrons: one of its own and one from oxygen [ note that hydrogen only needs 2 valence electrons to be complete instead of 8].
In metallic bonds between metals, the valence electrons move much more freely than in other bonds. This free characteristic makes metals how they are: ductile, malleable, sectile, conductive, etc.
Answer:
The answer would be A. the number of electrons in the outermost electron shell.
Explanation:
These are called valence electrons which are transferred, shared, and rearranged by creating covalent bonds producing new substances.

A good business atmosphere is an environment where everything is calm, maintaining, and positive. There also has to be good communication because, communication is key to a stress free atmosphere. everyone should work well and efficiently together. That is a good business atmosphere.
Hope this helps :)
