Fluorine atom requires one electron to make energetically stable outer orbit structure. Each atom starts out with an odd number of electrons in its valence shell: The two atoms can share their unpaired electrons to make a covalent bond: We note that the H atom has a full valence shell with two electrons, while the F atom has a complete octet of electrons. Cesium nitride, Cs. If the overall molecule is polar, the substance may have a higher melting point and boiling point than expected; also, it may or may not be soluble in various other substances, such as water or hexane. The Xe atom has an expanded valence shell with more than eight electrons around it. Breaking a diamond means breaking every bond at once. Four is the greatest number of bonds that is commonly made by atoms, so C atoms maximize their interactions with other atoms.
