4. Choose any 10 elements with atomic # less than or equal to 92 (Uranium) and make page about each element describing a few of their chemical characteristics (atomic
number, metal/nonmetal, # of valence electrons, etc.) AND a fun fact. Be sure to inclu-
the elements name, symbol, atomic mass and number. Remember on the first page
starting this section to describe what atomic # and mass #is! Total: 10 pages

explanation:

because it is

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.
