What couldn't Rutherford model explain?
The Rutherford model of atom has neither addressed the process of radiation of atoms nor could it explain the stability of the atom in spite of the revolving electrons around the nucleus. According to electrodynamics the electron should radiate electromagnetic waves. A simple calculation shows that an electron starting from a circular orbit of the size of an atom will spiral into the nucleus by radiating away its energy in a very short time, about 10-8 s. This makes stability of the atom impossible, which is not the case.
How large can atoms get?
Atoms can get larger by adding more protons, neutrons, and electrons. However, there is no theoretical limit to how large an atom could be, although the stability of such large atoms would be limited by factors such as nuclear forces and electron configuration.
How did Ernest Rutherford change atomic model?
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
When two or more atoms form together what do they make?
When two or more atoms form together, they make a molecule. This occurs through chemical bonding, where atoms share or exchange electrons to achieve stability. Different combinations of atoms can create a wide variety of molecules with distinct properties and functions.
Why was J J Thomson's model incorrect?
The model was incorrect for many reasons. The primary reason is because there is no cloud of positive charge. There are protons instead with a nucleus And also neutrons cod 6 is the best and godlike
What were drawback of atomic model discovered by JJ Thomson?
One drawback of JJ Thomson's atomic model was that it could not explain the distribution of positive charge within the atom. Additionally, it could not account for the stability of atoms with multiple electrons. Ultimately, Thomson's model was replaced by the more accurate and comprehensive model proposed by Ernest Rutherford.
Who suggested that atoms could desenigrate?
Ernest Rutherford
Why did Rutherford's model need to be modified?
Rutherford's alpha particle scattering experiment proved that the atom was mainly empty space, which cannot be allowed by the Thompson model. Thompson's model stated that atoms are positive spheres with electrons studded in them.

Problems with Rutherford model?
In Rutherford's model of the atom the electrons had a circular motion around the nucleus. By the laws of physics, if something is going in a circular motion then it must be accelerating and a particle that accelerates is losing energy. This means that the electrons that are revolving around the nucleus would eventually fall into the nucleus. Nucleus would eventually collapse. This does not happen therefore the Rutherford model was put aside.
Which fact about gold could not be discovered in Rutherford's experiment?
There are a few things that are true about gold that could not be discovered in Rutherford's experiment. There are solid atoms in the region that are called Nucleus.
What shortcomings in the atomic model of ernest Rutherford led to the development of niel's bohr's model?
One problem with Rutherford's model was that if electrons moved in such random orbits, they would emit electromagnetic waves, according to the laws of classical mechanics. No radiation was seen, and the release of radiation from the electrons would cause them to decay and lose energy. This would cause the electrons to spiral down to the nucleus, and destroy itself. This model said that all matter was unstable. Like Thompson's, Rutherford's model was still not able to explain atomic emission and absorption in the line spectra. He could not answer to why atoms produce light at specific, discreet wavelengths. He also could not explain why atoms emitted and absorbed at discreet wavelengths as opposed to bands of continuous wavelengths. Rutherford's discovery of the nucleus of the atom and his theory that electrons orbit around the positively charged nucleus led to Neils Bohr's idea that the electrons actually travelled in fixed energy levels, which did not cause electrons to lose energy while orbiting and also explained the light emissions of the atoms.
What best describes rutherford's model of the atom?
Rutherford's model of the atom proposed that atoms have a small, dense, positively charged nucleus at the center, surrounded by negatively charged electrons. This model suggested that electrons orbit the nucleus similar to planets orbiting the sun, but it could not explain the stability of atoms or the distribution of electron energies.
What were the defects of Rutherfords experiment?
One of the main defects of Rutherford's experiment was that the atomic model he proposed (with a dense, positively charged nucleus at the center orbited by electrons) could not explain the stability of atoms and the continuous emission of electromagnetic radiation. Additionally, his model did not account for the distribution of electrons in the atom and the specific energy levels they occupy. Finally, Rutherford's experiment did not incorporate quantum mechanics, which is essential for describing the behavior of particles at the atomic level.
Why Rutherford's and bohr model of atom were rejected?
Rutherford's model has a centralized nucleus that contains protons and neutrons with orbiting electrons. This is wrong because the electrons are shown in stable orbits and they actually exist in probability clouds.
Mention two defects in Rutherford atomic model?
according to classical theory, electrons being the charged particles should release or emit energy continuously and they should ultimately fall into the nucleus. if the electrons emit energy continuously, they should form a continuous spectrum but in fact, line spectrum was observed.
How did Rutherford discover that there was a dense solid nucleus of an atom?
He picked up a piece of metal and looked at it REALLY carefully, and he could see inside the atoms.
