What type of particle is emitted by each type of radioactive decay? a. alpha = nucleus of a helium atom beta = photon gamma = electron b. alpha = electron beta = nucleus of a helium atom gamma = photon c. alpha = nucleus of a helium atom beta = electron gamma = photon d. alpha = electron beta = photon gamma = nucleus of a helium atom

C. alpha = nucleus of a helium atom

beta = electron

gamma = photon

Answer : The correct option is, (C) alpha = nucleus of a helium atom, beta = electron,  gamma = photon

Explanation :

Alpha particle : It is also known as alpha radiation or alpha ray that consists of 2 protons and 2 neutrons that are bound together into a particle that is identical to the helium nucleus. It is produced in the process of alpha decay.

Beta particle : It is also known as beta radiation or beta ray. During the beta decay process, a high energy and speed electron or positron are emitted by the radioactive decay of atomic nucleus.

Gamma particle : It is also a gamma radiation or gamma ray that is arising from the radioactive decay of atomic nuclei. It has shortest wavelength waves and imparts high photon energy can pass through most forms of matters because they have no mass.

Hence, the correct option is, (C) alpha = nucleus of a helium atom, beta = electron,  gamma = photon

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

lol idk man i guess u gotta ask bill nye the science guy
