jj thos .. In 1904 proposed that an atom was a sphere of +ve electricity in which were embedded no of e-(ectron) sufficient 2 neutralize the +ve chrg the stability of the atom was ewplained as a result of the balace b/w the repulsive forces b/w the e- & their attraction toward the center of the +ve sphere . &compared with a "water melon" in which seeds r embedded or with a cake or pudding in which raisins are embedded
Ruther fords ;
1 )there must be sufficient enpty space within the atom
2) or small +ve charge in center
The New Model Army, organised by Oliver Cromwell, was a part of the Parliamentarian rebellion against the Royalists. The "old army", as you put it, did not answer to a Parliament - they were the Royalist army.
Rutherfords model (or the planetary model) of the atom is that the nucleus (with positive net charge) is very small and is surrounded by a number of electrons (each with a charge of -1). Rutherford came to this conclusion because during experiments where helium nuclei (alpha particles) were beamed at a gold foil, a very few (1 in 8000) were deflected by a large angle (more than 90 degrees) and most passed through the gold foil with no measurable deflection at all.
The usual idea of the atomic model is a nucleus composed of protons and neutrons, surrounded by electrons in orbit in shells of increasing diameter. This helps to visualise the difference between atoms. Quantum theory is that this simple model is not accurate, but it does have the virtue of being easily understood.
the speed and the memory it can store. also by how good the model is and if the upgrade is vista windows or lower upgrade.
remington model 512 value, as with all items, depends on condition. how good in the finish, wood, bore. Any rust/pitts. between $75 - $100 if good
The Rutherford model involve a positive nucleus separated from electrons.
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
Rutherfords Model is Rutherfords Model... thats it, its just a model.. go look it up on google images im sure you will figure it out by then.
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
Thomson's model was the "Plum Pudding model" because it had electrons "floating" around in the ball, but Rutherford's model shows the electron shells, the nucleus, and the molecular particles: neutron, proton, and electron. Hope this helps!
Because Joel is the man
Rutherford's model was similar to Thomson's model in that both described atoms as having a positively charged center (nucleus) surrounded by negatively charged electrons. However, Rutherford's model differed in that he proposed that the majority of an atom's mass and positive charge was concentrated in the nucleus, with electrons orbiting around it, while Thomson's model suggested that the positive charge was uniformly distributed throughout the atom.
It described a nucleus surrounded by a large volume of space.
Niels Bohr introduced the notion of electronic orbits.
what is the difference between the memory store model and the working memory model?
i wish i knew
difference between holistic and medical models
