Help me please 1) information about the atomic structure (structure of the atom)

2) information about the periodic table of the elements and the classification of the elements​

Im sorry cant help you their

Explanation: i dont know how to answer that question with the wording/format you chose

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.
