After 1911 most scientists accepted the theory that the nucleus of an atom was very dense and very small and has a positive charge. What led scientists to accept this theory?

The breakthrough was the alpha particle scattering experiments of Marsden, Geiger and Rutherford. Basically they fired a beam of alpha particles (which are small, positively charged particles emitted by some radioactive sources), at a thin metal foil. Unexpectedly, instead of the slight scattering of the beam they expected, they found a very few particles were scattered back towards the source. They could only explain this if the metal atoms had a tiny central nucleus with a positive charge to repel the alpha particles. If you search you should be able to find Rutherford's own account of those experiments.

Which scientist or scientists described acids as substances that accept electrons pairs during the formation of a covalent bond?
Lewis :D
Why is the electronegativity of nonmetal higher than metal?
All metal has less number of proton when compared to non-metal, in another word all metal has low effective nucleus charge compared to non-metal, the high effective nucleus charge causes the non-metal has higher electronegative than metal as the term electronegative means the ability to accept electron from others and in order to do that the nucleus of the atom ( effective nucleus charge ) must be high enough. That explain why metal donate electron due to low electronegative and non-metal accept electron due to high electronegative.
A Bronsted-Lowry base is a?
A Bronsted-Lowry base is a chemical species which has the ability to accept a proton (positive hydrogen cation). You could also say it as being a "proton acceptor" !
Why are amines more basic than ammonia?
Ammonia acts as a Brønsted-Lowry base as it can accept a proton to form an positive ammonium ion. Amines act in a similar manner, but the hydrocarbon segment lends a larger molecule to help distribute the positive charge, leading to a more stable cation.
What are substances that releases positively charged hydrogen ions while what are substances that accept positively charged hydrogen ions?
A compound that accepts hydrogen ions (which are always positive) is a Lewis Base. A compound that lets go of a hydrogen ion is a Lewis Acid.
What is Theory that many scientists accept as an explanation for the origin of the universe?
The Big Bang theory is the most widely accepted.
Why do scientist accept the capture theory?
They generally don't. The Giant Impact Hypothesis is generally accepted amongst scientists.

Why was wegener's theory not accepted by all scientists?
Wegner's theory was not accept because he didn't have much evidence to support his theory with and scientists thought that there might have been a land bridge between the continents. Another reason to why his theory was rejected was that he was a foreigner, by that; the scientists didn't really take him seriously.
Is a scientist hypothesis accepted if there is no way to prove that they hypothesis is wrong?
If you develop an experiment that truly demonstrates that the hypothesis is wrong*, then the hypothesis will lose its acceptance in the scientific community. * Such an experiment would have to be repeatable by other scientists AND accepted by interested scientists as a proof that the hypothesis is wrong.
