For instance‚ drugs such as amiodarone‚ cytokines and lithium affect the thyroid function in the body and most cases triggers hypothyroidism especially in the elderly. However‚ hypothyroidism is also in some cases induced due to over treating it by use of thyroid-blocking drugs (Garber‚

number (n). 2. (a) The first shell electrons in Lithium are the closest electrons to the nucleus. In addition‚ there are proportionally more protons to electrons. This pulls the electrons even closer to the nucleus. And in Potassium‚ the outer shell electrons are a substantial distance from the nucleus. There are a greater number of protons than electrons; however‚ the large number of electrons dissipates the effect. This is in addition to Lithium being a much smaller neutral atom than Potassium

1. Sodium and potassium are the most frequently ecountered alkali metals‚ though rarely as the metal. Why these elements are rarely found as the metal? (Refer to the relative measurements tabulated in the form of electronegativities‚ ionization energies‚ or reduction potentials). These are due to the fact that their outer most orbital (ns1 valence electron configuration) has tendency to lose electron very easily and make stable configuration. The single valence electron is relatively far from the

used to determine which substances were endothermic or exothermic when dissolved in water. According to the simulation‚ sodium chloride and ammonium chloride was observed to be endothermic. Calcium chloride‚ sodium acetate‚ sodium carbonate‚ and lithium chloride was observed to be exothermic. As sodium chloride and ammonium chloride was observed to be endothermic‚ those two salt substrates was not used in the experiment as the goal of the experiment was to increase temperature‚ not decrease it.
