The chemical bonds between atoms of elements involve a transfer or sharing of valence of electrons. This give a compound different properties from its elements.
WebIn F 2 O, the electronegativity of F is more than oxygen. Hence, each of F atom will attract one electron from oxygen i.e. F will show -1 oxidation state and O will show +2 oxidation state. Whereas, in the case of Na 2 O, oxygen is highly electronegative than sodium atom.
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative reactive element, it is extremely reactive, as it reacts with all other elements except for the light inert gases. … See more Electron configuration Fluorine atoms have nine electrons, one fewer than neon, and electron configuration 1s 2s 2p : two electrons in a filled inner shell and seven in an outer shell requiring one more to be … See more Early discoveries In 1529, Georgius Agricola described fluorite as an additive used to lower the melting point of metals during smelting.
