Amolecule has four bonded atoms around a central atom. the central atom does not have any lone pairs of electrons. what is the geometry of the molecule?

the answer is a for sure mark brainliest i had got this right on usatestprep

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.
