Lead & acid.
This depends on the application of the electrolytes. In case of battery it is good for us to have more electrolytes so longer battery life. For human body excessive electrolytes can be harmful.
There are many elements that are toxic to humans. A few of these elements are: arsenic, mercury, lead, and radium.
Hydrogen and helium
noble elements are the stable elements. They are found in group 18 in the periodic table.
fungi is found on coins. it can be very harmful

You can get histoplasmosis from the fungus Histoplasma capsulatum. The fungus is typically found in soil and when disturbed releases harmful elements into the air that can then be inhaled by humans.
Potentially toxic elements found in Windex are: isopropanol, ethylene glycol n-hexyl ether, and 2-Butoxyethanol. However, these ingredients are not very harmful unless swallowed.
if you open up a battery u wont die but yes the chemicals found inside can be extremely harmful. but when you open up a battery the are usually a steel rod inside and many other things which i can not be bothered to say but if u really want an answer reply :)
No, algae are not harmful unless it dies. (Found this answer on Yahoo.com)
Yes, and so is touching it.
O3 is the gas mentioned above. It is the gas which protects us from harmful UVB rays in the Stratosphere. But when found closer can be harmful.
Lead will certainly be found in your car battery.
Elements are found on the periodic table and have a chemical bond
sulphide acid and hydrogen sulfate are harmful materials that can harm a metal.
