Any of the other alkali metals not mentioned (I.e. rubidium, caesium or francium). They are all group one metals meaning that they contain one valence (outer shell) electron so they will have similar properties. Francium is the most reactive alkali metal while lithium is the least reactive (if you’d like me to explain that let me know :) )

A common antacid contains the acid-neutralizing agent sodium hydrogen carbonate. Write the chemical formula for sodium hydrogen

kaheart [24]

Sodium hydrogen carbonate has:
$sodium \: ion ( {Na}^{+}), hydrogen \\ ion ( {H}^{+}), and \: carbonate \\ ion ( {CO3}^{2-})$
The + from Na+ and + from H+ makes 2+, and therefore the 2- from CO3 evens the charges to neutral.

Not to be confused with Sodium Carbonate, (Na2CO3), which lack an H, Sodium Hydrogen Carbonate is sometimes shortened to just Sodium Bicarbonate. It is used in the kitchen (cooking) as "baking soda."

Formula: NaHCO3
