Which is more chemically active Ca or Rn?

Ca (calcium) is more chemically active than Rn (radon). Calcium is a reactive alkaline earth metal that readily forms compounds with other elements, while radon is a noble gas known for being chemically inert due to its full valence shell.


What is hardness of radon?

Radon is a colorless, odorless, tasteless gas, so it does not have a hardness like a mineral or metal. Instead, radon is classified based on its radioactivity and health impact due to its ability to emit ionizing radiation.


What does it mean if you have radon in basement?

Having radon in the basement means that there are elevated levels of the radioactive gas, which can pose a health risk when inhaled over long periods. Radon is the leading cause of lung cancer in non-smokers and it's important to mitigate its presence to reduce the risks to you and your family. Testing for radon and implementing appropriate measures like ventilation or radon mitigation systems can help lower levels in the basement.


Is Radon abundant?

A2. Radon is a decay product of Uranium, and is about 6 radioactive decay steps from U238. The Uranium occurs in some granite rocks, and as buildings are often made from this durable rock, Radon is generated from the building fabric. It is considered that exposure to Radon gas is second only to cigarettes as the cause of lung cancers in the US. Some unfortunate towns, such as Dundee, sit on the granite and build the houses of it, and this is a serious local problem. Basements and attics should have adequate ventilation to remove the gas.It is not an abundant gas, and perhaps there are some tens of grams of Rn in the Earth's atmosphere. This eventually decays into lead, and is continuously replaced by new Rn from U decay.


Is Ca a double cation?
