Gamma rays. Since they are electromagnetic waves, they travel at the speed of light.
Gamma Ray
Electrons are not directly involved in the creation of alpha, beta, or gamma radiation. Alpha radiation consists of helium nuclei (2 protons and 2 neutrons), beta radiation is made of electrons (beta-minus) or positrons (beta-plus), and gamma radiation is a high-energy electromagnetic radiation.
The gamma ray is not a particle but is just an EM wave that transmits energy.
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
Alpha and Beta Radiation are types of ionizing radiation. They are both charged particles though Alpha is heavier than the particle Beta.
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
Alpha and beta are not electromagnetic radiation.
Gamma Ray
ernest Rutherford is the answer....
The three main types of radiation are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of alpha particles, beta radiation consists of beta particles, and gamma radiation consists of gamma rays.
a. an alpha particle
Electrons are not directly involved in the creation of alpha, beta, or gamma radiation. Alpha radiation consists of helium nuclei (2 protons and 2 neutrons), beta radiation is made of electrons (beta-minus) or positrons (beta-plus), and gamma radiation is a high-energy electromagnetic radiation.
The gamma ray is not a particle but is just an EM wave that transmits energy.
Alpha particles have the least penetrating power compared to gamma rays and beta particles. This is because alpha particles are heavier and more positively charged, which makes them easily absorbed by materials, including skin.
They are Alkali metals, Alkaline Earth metals, and Carbon 16. ----
The gamma ray is not a particle but is just an electromagnetic wave that transmits energy.
Various radioactive substances such as Plutonium and Uranium give off a combination of alpha, beta and gamma rays as the isotope decays.
