What is the net change that occurred during the fusion process in the sun

Answer is: Four hydrogen nuclei join to form a helium nucleus, two neutrinos, and energy.

Hydrogen fusion cycle involves four hydrogen nuclei and two electrons and form of helium nucleus, two neutrinos and six photons.

This process occurs in three steps:

1) Fusion of hydrogen into deuterium.

2) The the formation of helium-3.

3) Recombination of two helium-3 into one nucleus of helium.

This fusion nuclear reaction is in the inner core of the Sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
