Clearly explain how hydrogen bonds are formed, using water as an example. [Hint: Include the electron structure of water and include what relative electronegativities are and how they work to develop a partial + and partial - charge].
The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)
11H and 13H have (a) different chemical properties because they have different atomic numbers (b) the same chemical properties because they have the same number of valence electrons (c) different chemical properties because they differ in their number of protons and electrons (d) the samechemical properties because they have the same atomic mass (e) the same chemical properties because they have the same number of protons, electrons, and neutrons
