Write the nuclear equation for the most likely mode of decay for each unstable nuclide. b. Ra-216

검증된 단계별 안내

Identify the type of decay: Radium-216 (Ra-216) is likely to undergo alpha decay because it is a heavy nuclide.

Write the general equation for alpha decay: In alpha decay, a nucleus emits an alpha particle, which is a helium nucleus \( ^4_2\text{He} \).

Determine the daughter nuclide: Subtract the mass number and atomic number of the alpha particle from Ra-216. The atomic number of radium (Ra) is 88.

Calculate the new mass number: \( 216 - 4 = 212 \).

Calculate the new atomic number: \( 88 - 2 = 86 \). The element with atomic number 86 is radon (Rn), so the daughter nuclide is Rn-212.

Nuclear Decay

Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This can occur through various modes, including alpha decay, beta decay, and gamma decay. Each mode involves the transformation of the nucleus, resulting in the emission of particles or electromagnetic radiation, leading to the formation of a different nuclide.

Nuclear Equation

A nuclear equation represents the transformation of one nuclide into another during a decay process. It includes the symbols for the initial nuclide, the emitted particles, and the resulting nuclide, ensuring that both mass and atomic numbers are conserved. Writing a nuclear equation for Ra-216 involves identifying the decay mode and accurately depicting the reactants and products involved.
