A storm that stays longer over coasts is a more dangerous storm. Is this statement true or false?

I think it is true, but I am not to sure.

True

Explanation:

Tornadoes are far and away the most dangerous storms in terms of deaths and injuries by an order of magnitude. Hurricanes, typhoons, and storm surges cause the most property damage, droughts and floods cause the most crop damage

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
