Who proposed that atoms are tiny solid ball?
John Dalton thought that atoms were like little marbles, and also studied how elements combine to form compounds.
What Greek philosopher was the first person to propose the idea that matter is made of tiny individual particles called atoms?
Greek philosopher Democritus.
john Dalton is an English school teacher then he formulated the ancient atomic theory of matter< > : )
it is simply a small cluster of nuetrons and protons held together by nuclear force
Thomson proposed that an atom was a ball of positive charge with electrons embedded in it. Some other things he discovered are: - that atoms are made of even smaller subatomi…c particles. - electrons which are tiny negatively charged particles with mass.
The dynamide model was proposed by Philipp Lenard in 1903. Despite this failed model, Lenard won the 1905 Nobel Prize in Physics for his work on cathode rays.
\nIn extreme cases, it is an actual medical problem in males called Hypogonadism. It is usually caused by a major deficiency of sex hormones and can result in infertility, mem…ory loss, depression, muscle loss, etc... It can also be congenital- something that person was born with, it too results in infertility and various health problems.\nOtherwise, the size-range for normal, healthy testicles varies widely. Difference in hormone levels as well as genetics can determine the size of a mans testicles.
If you are refering to the Bohr-Rutherford model, then I would say that it was developped by Neils Bohrn and Ernest Rutherford.
In World War 2
In the nucleus of an atom, there are protons and neutrons. The protons have the positive charge whilst the neutrons have a neutral charge (no charge).
The core of an atom where the neutron and proton are locate are solid in comparison to the electron shell, if you search for information about work carried out by Ernest… Rutherford and the Rutherford atomic model this should explain it. I think the current model of the atom is wrong, but lets see what the LHC provides.
