Sodium hydroxide. One makes chlorine bleach by reaction of sodium hydroxide and chlorine in water . The product is a 50/50 mix of sodium chloride and sodium hypochlorite solution, plus a big excess of NaOH. Bleach makers dilute the solution down to 5% NaOCl. One has to be careful to keep the pH high, or the NaOCl will react with H+ to form Cl2 again.

To bleach something is to remove or lighten its colour, sometimes as a preliminary step in the process of dyeing; a bleach is a chemical that produces these effects, often via oxidation. Common chemical bleaches include "chlorine bleach", a solution of sodium hypochlorite (NaClO), and "oxygen bleach", which contains hydrogen peroxide or a peroxide-releasing compound such as sodium perborate or sodium percarbonate. Bleaching powder is calcium hypochlorite.

The active ingredient in household bleach is sodium hypochlorate. So your alkali metal would be sodium.
