What heavier element is created when hydrogen atoms fuse together in the sun’s core?

sergey [27]

Answer:

Helium is created from hydrogen in the sun's core.

Four hydrogen-1 nuclei fuse to produce

one helium-4 nucleus, two neutrons,
two positrons, and
two electron neutrinos.

Explanation:

Step One:

${\rm ^1_1 H + ^1_1 H\to ^2_1 H + e^{+}} + v_e$ .

Two hydrogen-1 nuclei fuse. One proton will convert to a neutron. The products will be

one hydrogen-2 nucleus,
one positron, and
one electron neutrino.

Step Two:

$\rm ^1_1 H +^2_1 H \to ^3_2 He$ .

There are plenty of hydrogen-1 nuclei available in the core of the sun. The hydrogen-2 nucleus from step one will fuse with a hydrogen-1 nucleus. The product is
