∙ 14y agoThis would be the Rutherford gold foil experiment: consult http://en.wikipedia.org/wiki/Rutherford_experiment Fun fact: Rutherford did this experiment (and made the history and chemistry books) when he was an undergrad! I spent the better part of two years in college working in a lab and I didn't even publish a single paper!

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.
Positively charges central part of the atom?
Protons are the positively charged particles located in an atom's nucleus.
Why does objects become positively charged if they lose electrons?
Losing electrons the positive charges become bigger than negative charges.
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.
Who discovered the positive charge of a nucleus?
Ernest Rutherford is the scientist that discovered the positively charged nucleus.
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.

What object repels a positively charged object?
A positively charged object. Like charges repel.

Does Rutherford's model have electrons with negative charges?
Yes, it is true.
What would happen if you touch the knob of a positively charged electroscope with another positively charged object?
Like charges repel. Unlike charges attract. Therefore, you would expect them to repel each other.
Is all atomic nuclei are positively charged?
Yes, because within a nucleus 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 not WITHIN the nucleus, so the nucleus will be positively charged.
What is Thomson atom?
J.J. Thompson was the person who suggested the plum pudding model for the atomic structure. He declared that the electrons are located between a cloud of the positive charges. This model was proven incorrect from the alpha particle experiment done by Ernest Rutherford.
Atoms have a higher number of positive charges than negative charges?
Cations, positively charged atoms e.g. Na+. The positive charges are the protons min the nucleus and the negative charges are electrons.
Why does objects become positively charged if they lose electrons?
Losing electrons the positive charges become bigger than negative charges.
