Probably soft, since the other members of the alkaline earth metals (Ca, Ba, Sr) are soft metals.
Radon is a very heavy gas, several times heavier than air. When radon seeps into a basement as a result of low-level radioactive decay within rocks such as granite, it tends to be trapped there. This is especially true as homes are sealed tighter with insulation and weather strips. A full time ventilation system that circulates air from around the outside of basement floor and walls will stop radon buildup.
Yes it is. In solution it is found as Ca++.
Rn is the chemical symbol for Radon, an inert gas. Inert gasses don't like to react with other elements, therefore it is Calcium, whose chemical symbol is Ca, that is more reactive.
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.

I love Marcel Adler
La mirada, he was born in La Mirada, CA, but he actually attended La Serna High School in Whittier, CA.
