The Sun emits extremely large amounts of energy through solar flares. Which of the following reactions results from alpha decay?

Correct Answer: D. 263Sg -> 259Rf
Alpha decay results in the ejection of an alpha particle from the nucleus. The alpha particle contains two protons and two neutrons. The two protons would decrease the atomic number by two and the total mass number of the atom would decrease by four. The only choice that satisfies both of these requirements is D, 263Sg -> 259Rf.
