I would like if you guys could answer me this question or give me a website where I cold find the answer. Lead, mercury and plutonium are very harmful elements, but when you cobined them with what do they become harmless? The element with which they must be combined does not have to be the same for all three, I already tried searching on several websites like newton but I could not find any specific answer,I know that mercury is not extremely harmful in low amounts. I really hope you guys could help this is not homework but a personal quest.

I think you need to start by defining the problem a little tighter. What do you mean by 'harmful' and 'harmless'. A place to start might be by finding out what is meant by the terms 'Hazard' and 'Risk' as these have specific meanings and are often mis-used, especially by the press.

This then might lead you to decide for whom or what you are tying to minimise the risk.

To take an example. One way to immobilise lead is to have the metal as a brick and perhaps paint it with gloss paint. It is stable in this form and unless the brick is chewed the lead is very unlikely to be injested. The paint stops the small transfer to hands that might occur during hamdling. One of the hazards that remains is that lead is dense and the brick may have considerable mass so could break a foot if dropped.

Hope this helps.

To find out if there are any substances that can render lead, mercury, and plutonium harmless when combined with them, you can follow these steps:

1. Start by searching for each element individually and their potential combination with other substances. Use trustworthy scientific websites or databases for accurate information. For example:
- Search for "lead combination with other elements" or "lead chemical reactions."
- Search for "mercury combination with other elements" or "mercury chemical reactions."
- Search for "plutonium combination with other elements" or "plutonium chemical reactions."

2. Explore the search results and scientific resources that come up. Look for any information on the reactions or compounds formed when these elements are combined with other substances.

3. Check for research papers, scientific studies, or articles on the topic. These sources often provide detailed information about chemical reactions and potential ways to reduce toxicity.

4. Additionally, you could try searching for specific applications where these elements are rendered harmless or less toxic. For example, explore the field of environmental remediation, where substances are used to mitigate the harmful effects of pollutants in soil or water.

Remember that combining these elements with other substances to render them harmless is a complex topic, and it might be challenging to find explicit answers or complete solutions. It is important to note that some compounds or reactions might reduce toxicity but not completely eliminate it.
