A thorium-232 nucleus decays by a series of α and β⁻ emissions until it becomes lead-208. How many α emissions and how many β⁻ emissions occur in this series?

Respuesta :

Answer:

232nucleus thingys

Explanation:

B-emissions occur when friction stimulates gas and it hydrophetic cosmetics combine and it emits toligraphics

Six (6) α emissions and four (4) β emissions occur in the series where thorium-232 decays to lead-208

Radioactive decay

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation.

An alpha (α) emission

Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby decays into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.

A beta (β) emission

Beta decay or β-decay is a radioactive decay in which a beta ray is emitted from an atomic nucleus.

The reaction that represents the series of emissions that occur when thorium-232 nucleus decays to form lead-208 is

²³²₉₀Th → ²⁰⁸₈₂Pb + 6 (⁴₂He) + 4 (⁰₋₁e)

NOTE: ⁴₂He represents α emission while ⁰₋₁e represents β emission

Hence, six (6) α emissions and four (4) β emissions occur in the series where thorium-232 decays to lead-208.
