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

  • one helium-3 nucleus.

Step Three

\rm ^3_2 He + ^3_2 He \to ^4_2 He + ^1_1 H + ^1_1 H.

Two helium-3 nuclei from step two react with each other. The products are:

  • one helium-4 nucleus, and
  • two hydrogen-1 nuclei.

The overall reaction will be:

{\rm 6\; ^1_1 H \to ^4_2 He + 2\; ^1_1 H+2\; e^{+}}+v_\text{e}.

{\rm 4\; ^1_1 H \to ^4_2 He + 2\; e^{+}} + v_\text{e}

In other words, hydrogen nuclei in the core of the sun fuse together to form helium.

In the ocean, light is used by phytoplankton in order to produce sugar.  10% of the energy from the sun is available to the zooplankton that eat the phytoplankton, the rest of the energy is lost as heat or through powering body building/functions/reproduction.  Whatever eats the zooplankton receives 10% of that energy in order to grow
