Radon is a radioactive gas. I occurs naturally in the soil from decaying uranium deposits. Radon is a chemical element with the symbol Rn and atomic number 86.
In modern homes radon can be a major indoor air pollutant. Radon seems to be the cause of about 10% of the lung cancer cases in North America.
Just the facts, Radium stops cancer in its tracks.

Yes, radon can enter a home with an exposed basement through cracks in the foundation or gaps in the basement floor. It is important to test for radon levels in basements, especially if they are unfinished or exposed. Mitigation measures such as sealing cracks and installing a radon mitigation system can help reduce radon levels in the home.
In most places, landlords are not required to test for radon. However, it is a good practice to ensure the safety of tenants and the property. Offering radon testing as part of the rental agreement or working with tenants to address any radon issues can help create a healthy living environment.
Boron is an element that exhibits properties of both metals and non-metals. It can form covalent compounds like non-metals but also has some metallic properties, such as being a good conductor of electricity under certain conditions.

It is not, radon is very harmful because it is radioactive.

Based on the properties you described, the unknown element is likely a metal. Metals are typically shiny and good conductors of electricity. You could also predict that it is likely malleable and ductile, as these are common properties of metals.
because precent
The element that fits this description is silver. Silver is part of Group 11 and is known for its shiny appearance, malleability, and excellent conductivity of heat and electricity. It has an atomic number higher than cesium and lower than radon.
No good, no bad facts; francium is a very rare chemical element, also very unstable. The chemistry of francium is largely unknown. But is a radioactive element and the radioactivity is frequently dangerous.
[read this, if you don't think it sounds good, don't use it or if it does not make good sense do not use it but read it first . THANK YOU!] What i think the statement means by is that the properties of salts are formed when an element in the group under sodium or magnesium in the Periodic Table combines with an element under fluorine.
