Gamma rays are

Alpha decay makes an element’s atomic number

Alpha decay makes an element’s mass number

Gamma decay makes an element’s atomic number

Electron capture makes an element’s atomic number

What term was coined by the Curies for the spontaneous emission of penetrating rays from the nuclei of atoms?

keeps the mass number the same, reduces the atomic number, and produces a neutrino

consists of high-speed electrons

forms a particle with a positive charge but low mass

most common type of decay in elements with Z>83

What is it called when an atom of one kind of element changes into a different element as a result of a nuclear reaction?

What do we call the smallest mass of fissionable material that can sustain a chain reaction?

When a beta particle is emitted, the atomic number of the remaining element increases by one.

Electron capture occurs when the nucleus pulls in one of the closest electrons, which then combines with a neutron to form a proton.

Scientists believe that beta particles are nothing more than ________ that have formed in the nucleus.

What is the number of neutrons in the isotope ²³⁵U?

Sometimes called a thermonuclear reaction

Gamma radiation has more penetrating power than the other types of radiation.
