This is essentially a helium nucleus. _____ _____ (2) (b) Alpha particles are one type of nuclear radiation. So for example if a beryllium atom (atomic number 4) went through alpha decay it would become helium (atomic number 2). Example: Helium-4 Diagram of helium-4 atom. Since, the atom of hydrogen element contains 1 proton, the number of an electron will be the same. A major challenge before the scientists at the end of the 19th century was to reveal the structure of the atom as well as to explain its important properties. Created by.
