What changes in a radioactive material to make it emit radiation?
Due to unstable atomic structures (or a weak nuclear force), radioactive materials release alpha particles as radiation.
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.
What substance does uranium and plutonium release?
The elements emit especially alpha particles.
Which isotope will spontaneously decay and emit particles with a charge of 2?
220 Fr
Why synthesized isotopes emit alpha and beta particles?
All radioactive isotopes are unstable and they decay to a stable isotope emitting particles.
What energy produced by the vibrations of electrically charged particles?
Such particles will emit electromagnetic waves.
What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
What particles can thorium emit?
Alpha particles but also electrons and gamma radiations (Th 232).
What causes the lights?
The Sun's magnetic field produces charged particles and these charged particles are usually radiated out into space. Sometimes these charged particles may be caught in Earth's magnetic field and as they enter the upper atmosphere of Earth, they are in contact with other gases in the upper atmosphere and emit light and colors. The solar wind reacts to the Earth's magnetic field and then spreads across the ionosphere (the upper, charged layer of our atmosphere).
At what temperature does Lithium-6 emit radiation?
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing radiation.
Why do galaxies emit radiations?
Because galaxies include stars, clouds of hot gas, and free charged particles sailing through magnetic fields, and each of those emits radiations.
What changes in a radioactive material to make it emit radiation?
Due to unstable atomic structures (or a weak nuclear force), radioactive materials release alpha particles as radiation.
What particles does americium give off?
Americium emit alpha particles and gamma radiations.
What are atoms that emit particles and energy from their nuclei?
radioactive
What are the physical characteristics of the material?
- a radioactive material emit nuclear radiations as alpha, beta, gamma, neutrons - a radioactive material disintegrate in time
What are some important fact about the northern light?
It's caused by charged particles coming from the sun being diverted into the Earth's atmosphere by its magnetic field, and collided with atoms in the atmosphere to emit light.
How is californium radioactive?
Californium emit alpha particles and neutrons.
