First one, 6.250 * 10^(-4). Second one, 9.532 * 10^6. Third one, 4.38904 * 10^5. Forth one, 4.5833 * 10^(-3). The zero before first non-zero number can ignore.
When gasses are heated they emit only certain wavelengths of light (an emission line spectrum). Different gasses emit different wavelengths. A cool object (gas or solid) can absorb some of the light passing through it. The temperature of an object is a measure of how much energy its atoms have.

The type of decay which has the greatest mass is the alpha decay. An unstable
nucleus loses the most mass if the nucleus emits an alpha particle. This type
of decay has the largest mass among the radioactive
decay. When this particle is emitted from a nucleus, it loses two protons
and two neutrons therefore large amount of mass is lost.
