When atoms of beryllium are bombarded with alpha particles an atom of carbon is produced and a neutron is emitted What kind of nuclear reaction occurred?
Nuclear Fission. The Nucleus of the Atom has been split apart.
Why Rutherford does not use beta particles for scattering on gold foil?
Rutherford did not use beta particles for scattering experiments on gold foil because beta particles, being charged electrons, would have been deflected significantly by the electric fields of the atomic nuclei. Instead, he used alpha particles, which are positively charged and much heavier, allowing for a more straightforward interpretation of their scattering patterns. The interactions of alpha particles with the gold foil provided clearer insights into the structure of the atom, leading to the discovery of the nucleus. Additionally, alpha particles have a higher energy, which enhances their ability to penetrate the foil.
How many crystals have been identified?
4000
Whats the smallest particle of an atom?
Smallest particles in an atom are named as subatomic particles. They have been categorized into four. They are photons, leptons, mesons and baryons. Baryons are further classified into nucleon and hyperon. Photon is the smallest one whose rest mass is zero. Though it does not have mass, it has momentum. The energy content of a photon is mainly decided by the frequency of the radiation. So E = h v. v (nu) is the frequency Leptons are some how heavier but lighter than mesons. Electrons, positrons, neutrino, muons all come under this category Mesons have different types such as pi meson, eta meson, k meson etc Baryons have nucleons (protons and neutrons) and hyperons. (much heavier than nucleon) Apart from these there are strange particles and these are being studied and science now and then comes across new discoveries of subatomic particles. So far more than 100 particles have been discovered.
What will atoms do when put in ice?
This question shows a lack of understanding of what atoms are. All substances are made of particles (atoms are one type of particle). When a substance freezes the particles take up fixed positions in a lattice, but continue to vibrate. The solid is only ice if the particles are water molecules.
What structure of the atom has been described as having a dense center that contains subatomic particles?
The structure of the atom that has been described as having a dense center that contains subatomic particles is the nucleus. The nucleus is composed of positively charged protons and neutral neutrons, tightly packed together in the center of the atom.

What is the instrument that first took a picture of an atom?
So far, no picture of an atom has ever been taken. Atoms are fundamental particles which have only been visualized and not seen.
Are there the same amount of protons as there are of electrons in and atom?
NoYes. A neutral atom will have the same number of protons and electrons.
Why is Indirect evidence important in the study structure of the atom?
The atom is far too small to ever be examined directly. The diameter of a typical nucleus is only about 1/100,000 of the diameter of the entire atom and if an atom were magnified until it was as large as a football stadium, the nucleus would be about the size of a grape. Nearly all evidence of an atom's structure has been theorized.

Suppose Rutherford had not seen any alpha particles deflected back from the gold foil. How would this most likely have affected scientific understanding of the structure of an atom?
If Rutherford had not observed any deflection of alpha particles, it would suggest that the positive charge in an atom is spread out uniformly, rather than concentrated in a small nucleus. This would likely lead to the continued acceptance of the plum pudding model of the atom, proposed by J.J. Thomson, where positive charge is distributed evenly throughout the atom. The discovery of the nucleus and the planetary model of the atom would have been delayed.
How many alpha particles are produced as one atom of uranium-238 decays to an atom of lead-206?
4 alpha particles were emitted. This is known by the fact that an alpha particle ,on being given out, decrease the mass number of the element by 4.Hence the decrease in mass number in above question is 12 which itself states the answer that 4 alpha particles are emitted. The number of beta particles emitted are 3 beta particle have been emitted.
If the Thomson model of the atom had been correct Rutherford would have observed?
If the Thomson model of the atom had been correct, Rutherford would have observed that most of the alpha particles passed straight through the atom without being deflected or scattered. This would indicate a uniform distribution of positive charge throughout the atom, as proposed by Thomson.
Is Angela a UFO?
No. If it has a name, it's been identified. If it has been identified, it cannot be an Unidentified Flying Object.
