The modern structure of an atom?

Question

the traditional model: What experimental evidence supports the idea of the existence of atoms, their structure and their subatomic particles, i.e., protons, neutrons, and electrons?

Anyone knows how to answer these? Does anyone knows a good link i can have so I can answer this question?

most particles are consisting of neurons and proteins. check williapedia for the most up to date information

Answer 2

decrease and paste from Wikipedia: In 1897, JJ Thomson, via his paintings on cathode rays, stumbled on the electron and their subatomic nature, which destroyed the considered atoms as being indivisible contraptions. Later, Thomson additionally stumbled on the existence of isotopes via his paintings on ionized gases. Thomson believed that the electrons have been disbursed frivolously throughout the atom, balanced via the presence of a uniform sea of useful cost. besides the undeniable fact that, in 1909, the gold foil test of Ernest Rutherford stated that the useful cost of an atom and maximum of its mass replace into concentrated in a nucleus on the centre of the atom, with the electrons orbiting it like planets around a sunlight. In 1913, Niels Bohr added quantum mechanics into this kind, which now stated that the electrons have been restrained to for sure defined orbits and would desire to no longer freely spiral in or out. In 1926, Erwin Schrodinger, utilising Louis DeBroglie's 1924 concept that electrons behave like waves in an atom, wrote out a wave equation for the electrons in an atom, which had strategies describing electron orbitals. A effect of this concept, mentioned via Werner Heisenberg a 300 and sixty 5 days later, is that that's mathematically impossible to acquire precise values for the two the region and momentum of a particle at any think approximately time; this grew to alter into familiar via fact the Uncertainty theory. instead, for any given value of place you would be able to desire to purely acquire fairly a quantity in all threat values for momentum, and vice versa. subsequently, the planetary kind of the atom replace into discarded in choose of one that defined orbital zones around the nucleus the place a given electron is likely to exist.

Answer 3

Go to Wikipedia and look up the elementary particles.
