Mary could do two types of experiments

<em>Type 1</em>. She could <em>hold the cation constant and vary the anion</em>.

She could try solutions of NaCl, NaBr, NaI, Na₂SO₄, Na₃PO₄, etc.

These experiments would tell her which <em>anions</em> are the best conductors.

<em>Type </em>2. She could <em>hold the anion constant and vary the cation</em>.

She could try solutions of NaNO₃, KNO₃, Mg(NO₃)₂, Ca(NO₃)₂, Al(NO₃)₃, etc.

These experiments would tell her which <em>cations</em> are the best conductors.

Why isn't hydrogen considered an alkali metal ?
Maurinko [17]
<span>Hydrogen isn't classified as an alkali metal because it exhibits several properties that are not found in the alkali metal group, including the tendency to be found as a diatomic molecule, a tendency to form weak bonds with other bound hydrogen atoms nearby, weak electromagnetism, a low activity series placement, and the tendency to be found as a gas. Because of all this, it's impossible to classify it with any group, although it does seem to be closest to nonmetals.</span>
