An α particle is the nucleus of 4He to how many protons, neutrons and electrons exist in an alpha particle b) what is the charge of an α particle in units of electric charge(C. coulombs). c) What is the force that keeps the protons and neutrons in an α particle?

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
