Deep in the core of the Sun, 620 million metric tons of hydrogen nuclei are converted into 616 million metric tons of helium nuclei every second. What happens to the "missing mass" in the Sun's core?
What number completes the missing part of this nuclear equation?: 24 Na → 20F + 42α 11 __ Enter answer below
In a hydrogen fusion reaction, two lighter hydrogen nuclei merge to form a heavier, more stable helium nucleus. The energy that is released in a hydrogen fusion reaction is Select one: O less than the
