Given the equation representing a nuclear reaction in

which X represents a nuclide:

²³²₉₀Th --> ⁴₂He + X

Which nuclide is represented by X?

Given the fusion reaction:

²₁H + ²₁H --> X + energy

Which particle is represented by X?

In which type of reaction do two lighter nuclei combine

to form one heavier nucleus?

Which nuclear emission has no charge and no mass?

Given the nuclear reaction:

⁹₄Be + X --> ¹²₆C +¹₀n

What is the identity of particle X?

When an alpha particle is emitted by an atom, the atomic

number of the atom will

What was the original mass of a radioactive sample that

decayed to 25 grams in four half-life periods?

Given the nuclear reaction:

¹⁴₇N + ⁴₂He --> ¹₁H + X

Which isotope is represented by the X when the equation is correctly balanced?

Which list of nuclear emissions is arranged in order

from the least penetrating power to the greatest penetrating power?

Alpha particles and beta particles differ in

After decaying for 48 hours, of the original mass of a radioisotope sample remains unchanged. What is the

half-life of this radioisotope?

True or False

Because of it's heavy mass, beta radiation is more penetrable than alpha radiation.

When an atom of the unstable isotope Na-24 decays, it

becomes an atom of Mg-24 because the Na-24 atom

spontaneously releases

Which particle(s) have no mass?
