When the radioactive isotope of Th-234 emits a beta particle to become Pa-234 it also loses a small amount of mass which is emitted as?
gamma radiation!
What has the greatest amount of kinetic energy?
Kinetic energy = one-half the product of an object's massand the square of its speed.So, the object with the greatest product of (mass) x (speed)2 has the greatest kinetic energy.
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
What happen to atomic number and mass number of nucleus when it emits electron?
"Number" goes up by one, mass stays the same.
An unstable nucleus loses the most mass if the nucleus emits what?
The greatest mass loss to a nucleus undergoing decay by emission happens through alpha radiation. In this case, the atomic mass is reduced by approximately 4. Emission of a neutron (rare) or proton produces a loss of about 1. Other emissions cause smaller losses.
What change in mass occurs when a radioactive atom emits an alpha particle?
4 from the alpha. Betas have negligible mass and gammas have no mass.
When the radioactive isotope of Th-234 emits a beta particle to become Pa-234 it also loses a small amount of mass which is emitted as?
gamma radiation!
What object in the solar system has the greatest amount of gravity?
That's the one with the largest mass - i.e., the Sun.
Which type of mass movement presents the greatest threats to life?
Avalanches produce the greatest amount of life loss if that is wat you are looking for also landslide are quite powerful :)
What has the greatest amount of kinetic energy?
Kinetic energy = one-half the product of an object's massand the square of its speed.So, the object with the greatest product of (mass) x (speed)2 has the greatest kinetic energy.
What change in atomic mass when an atom emits gamma radiation?
It remains the same.
What happens to the mass number of a nucleus when it emits an electron?
When a nucleus emits a beta particle (electron) it is a result of neutron decay. This decay will also release an antineutrino and a proton is left which increases the atomic mass by one thereby changing the element.
What happen to atomic number and mass number of nucleus when it emits proton?
Both get decreased as At. no = No. of Protons & At. mass = No. of protons + No. of neutrons in the nucleus.
Which planet has the greatest mass relative to earth?
Jupiter has the greatest mass relative to Earth.
How radio isotopes can be identified?
Radioisotopes are identified by the halflife, type of radiations emitted, energy of these radiations, spectrometry (mass, gamma, alpha), etc.
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
Which radioisotope has an atom that emits a particle with a mass number of 0 and a charge of plus 1?
19Ne
