Differentiate between an atom, isotope, element and alpha particle.
A uranium-238 atom can break up into a thorium-234 atom and a particle called an alpha particle, α-4. The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10^−27 kg). When an uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.6 × 10^5 m/s. How much of the uranium atom's internal energy is released in the...

The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10−27 kg). When a uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.2 × 105 m/s. Please give the answer in Joules
A thorium atom of mass 232.038 u decays by the emission of an alpha particle to a radium atom of mass 228.031 u. If the alpha particle has a mass of 4.0026 u, how much energy in J is released in the process? (Answer is 6.56 x 10^-13 J)
a proton and an alpha particle (a Helium atom stripped of its electrons) are accelerated through an electric potential difference of 20 MV. If the proton and alpha-particle start at rest, then what are their final speeds? answer is 62Mm/s (proton) and 44 Mm/s (alpha particle) .

The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10−27 kg). When an uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.1 × 105 m/s. How much of the uranium atom's internal energy is released in the breakup?...
Assuming that each atom that decays emits one alpha particle, how many alpha particles are emitted per minute by a 0.00304-g sample of 226Ra that is free from its decay products? The half-life of 226Ra is 1.60×103 y and the mass of a 226Ra atom is 226.025 u.
a proton and an alpha particle (the nucleus of a helium atom, containing two protons and two neutrons) traveling at the speed enter a uniform magnetic field. The velocity vector of each particle is perpendicular to the magnetic field. What is the ratio of the radii of their circular orbits (r proton/r alpha) ? ~ 0.5 ~ 1.0 ~ 1.5 ~ 2.0 ~ 4.0
An alpha particle (the nucleus of a helium atom) consists of two protons and two neutrons, and has a mass of 6.64×10−27kg. A horizontal beam of alpha particles is injected with a speed of 1.3×105m/s into a region with a vertical magnetic field of magnitude 0.180 T . A) How long does it take for an alpha particle to move halfway through a complete circle? B) If the speed of the alpha particle is doubled, does the time found in...
