The ion hte− is an amphiprotic species; it can act as either an acid or a base. (a) what is the ka for the acid reaction of hte− with h2o? (b) what is kb for the reaction in which hte− functions as a base in water? (c) demonstrate whether or not the second ionization of h2te can be neglected in the calculation of [te−] in a 0.10 m solution of h2te.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above
