What experiment conuirneced ernest rutherford that the atom has a small positively charges nucleus?
th gold foil experiment
What else can I help you with?
Why did Rutherford conclude that an atoms nucleus has a posotive charge instead of a negative charge?
when carrying out the alpha scattering experiment, he observed that some alpha particles got deflected from their course. as alpha particles are helium nuclei, they are positively charged. the fact that they deviate made him think that there might be some repulsion between the particles and the nucleus. as positive charges repel each other, he determined the nucleus to be positively charged.
What year did ernest Rutherford make a contribution to the atomic model?
He didn't exactly "discover" the nucleus. In 1911 he theorized about the atom having its positive charges in a very small nucleus. In 1921 he postulated about the existence of the neutron in the nucleus. The first experiment to split the atom in a controlled manner was performed by him and two students in 1932.
Are all atomic nuclei positively charged?
Yes, because within a neutron there are protons (which is positively charged) and neutrons (which has no charge). Protons give out positive charges and there are no negative charges inside the nucleus to balance it out. The electrons are surrounding the nucleus but no WITHIN the nucleus so the nucleus will be positively charged.
Do atoms that lose electrons become negativity changed?
No, they become positively charged, because electrons carry a negative charge, and by losing an electron they lose one of the charges that previously balanced out the positive charges from the protons, becoming a positively charged ion.
Positively charges central part of the atom?
Protons are the positively charged particles located in an atom's nucleus.
Who discovered the positive charge of a nucleus?
Ernest Rutherford is credited with discovering the positive charge of a nucleus through his famous gold foil experiment in 1909. This experiment showed that most of the mass and positive charge of an atom is concentrated in a small, dense nucleus at its center.
Does Rutherford's model have electrons with negative charges?
Yes, Rutherford's model of the atom proposed that electrons orbit a positively charged nucleus. Electrons were considered to have negative charges in this model.
What scientist described the atom as mostly empty space with small positively charged nucleus because of the positive charges of the protons was?
This description of the atom was proposed by Ernest Rutherford through his famous gold foil experiment in 1909. Rutherford's findings led to the development of the nuclear model of the atom, where electrons orbit a dense, positively charged nucleus at the center.
Which scientist was the first to conclude through experimentation that atoms have positive charges in their nuclei?
Hans Geiger and Ernest Marsden. Rutherford was the supervisor and explained the unexpected results, so his name is usually attached to the experiment as well, but it was Geiger and Marsden who actually did it.
Who came up with the idea of a nucleus of an atom?
The discovery of the nucleus is typically credited to Ernest Rutherford, an English physicist of the early 1900s. Rutherford first came up with the idea of a nucleus as a result of his gold foil experiments.
What is the name of he scientist that discovered that atoms have positive charges?
Ernest Rutherford was the scientist who discovered that atoms have positive charges through his gold foil experiment, which led to the development of the nuclear model of the atom.

Do positively charged objects attract each other?
No, positively charged objects repel each other due to the like charges. Like charges repel, and opposite charges attract.
Why did some of the particles get deflected in Rutherford experiment?
A beam of alpha particles shot through a thin thin thin gold foil will occasionally have a few coming close to the nucleus of a gold atom - and as alpha particles have the same charge as the nucleus there is a repulsive force, which forces the particle from its original course. To keep a graduate student busy (I believe it was Marsden) Rutherford asked him to investigate if there was any particles that got deflect through an angle larger than 90'. (A preposterous notion) An to his great surprise there was.
What object repels a positively charged object?
A positively charged object. Like charges repel.
How thales experiment produced static electricity?
Thales' experiment involved rubbing amber with fur, creating friction that transferred electrons from the fur to the amber. This resulted in the amber gaining a negative charge, while the fur became positively charged. The separation of charges created static electricity.
