add two curved arrows to the reactant side to illustrate the movement of electrons in the e2 reaction. there will be a total of three curved arrows, one of which is drawn for you.

the correct answer would be d. hope this !

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.
