Is the sun positively charged?

In summary, the proton-proton chain reaction in the sun produces two positrons for each helium nucleus, which then annihilate with free electrons. This results in the conversion of four protons into two protons and two neutrons in the helium nucleus, maintaining the overall proton to electron ratio. Despite this, the sun is claimed to have a neutral charge.

Hydrogen fusion as described by proton-proton chain reaction that dominates in the sun produces two positrons for each helium nucleus produced. These annihilate with free electrons while the number of protons remain the same. Over time the sun is supposed to become positively charged, yet the claim is that its charge is neutral.

What is the mechanism for maintaining the proton to electron ratio in the sun?
Thanks!

Two positrons: two electrons. What's your question?

This is the source of your problem-- the number of protons does not stay the same. The net result is 4 protons turn into 2 protons and 2 neutrons in the helium nucleus. The loss in protons matches the annihilation of electrons.

The end result of the reaction is a helium nucleus which contains two neutrons as well as the two protons.
In simplistic terms those neutrons could be considered as protons which lost their positive charge during the fusion process.
So overall no net change of charge has occurred within the Sun.

Thanks, that was embarrassing. I was researching something that touched this topic and must have been so distracted I counted wrong.

hey, it happens to all of us from time to time

and welcome to the Physics Forums :smile:cheers

1. Is the sun positively charged?

Yes, the sun is positively charged. It has a net positive charge due to the abundance of positively charged particles, such as protons, in its core.

2. What causes the sun to have a positive charge?

The sun has a positive charge due to the process of nuclear fusion that occurs in its core. This process releases a large amount of energy and creates positively charged particles, which contribute to the sun's overall positive charge.

3. How does the sun's positive charge affect us on Earth?

The sun's positive charge does not have a direct impact on us on Earth. However, it does play a role in the formation of the Earth's magnetic field, which helps protect us from harmful solar radiation.

4. Can the sun's positive charge change?

The sun's positive charge can change, but it does so very slowly over millions of years. This is due to the constant fusion reactions occurring in the sun's core, which contribute to its overall positive charge.

5. Is the sun's positive charge the same as its electric field?

No, the sun's positive charge and its electric field are not the same. While the sun's positive charge is a result of the abundance of positively charged particles, its electric field is a result of the interaction between these particles and the Earth's magnetic field.
