Rubidium is not typically found in common household items. It is a rare alkali metal that is mainly used in specialized scientific and industrial applications, such as in atomic clocks and research experiments.
Household items that contain alkali earth metals include toothpaste (fluoride containing calcium), antacids (containing magnesium or calcium), and some cleaning agents (containing calcium, magnesium, or barium).
The most important alkali - sodium hydroxide - can be used at home to clean drains and conducts; also with sodium hydroxide and residual organic fats, it is possible to make soap.
Some household items that contain chlorophyll include green leafy vegetables like spinach, kale, and broccoli, as well as green herbs like parsley and mint. Chlorophyll can also be found in certain algae and seaweed-based products.
Technetium is not commonly found in household items as it is a rare and radioactive element. Its most common application is in nuclear medicine for diagnostic imaging.

Many cleaning products such as oven cleaner contain sodium hydroxide (NaOH). Also, antacids contain a base (base = alkaline) to reduce the acidity of the stomach.
