Beta particles are emitted from radioactive Atom P when it disintegrates spontaneously to form non radioactive Atom Q. Which of these statements is most likely correct about Atom P and Atom Q?
Select one:
a. The nucleus of Atom P emits neutrons and protons.
b. The nucleus of Atom Q emits neutrons and protons.
c. The nucleus of Atom P is more stable than the nucleus of Atom Q.
d. The nucleus of Atom Q is more stable than the nucleus of Atom P.

Respuesta :

Answer: option d: The nucleus of Atom Q is more stable than the nucleus of Atom P.

Explanation:

Atom P is radioactive and disintegrates, it emits beta particles (high speed electrons or positrons) because it is not stable. On disintegration, it forms a stable Atom Q which is non-radioactive and thus it does not disintegrates further.

Thus, the correct option is only d. The nucleus of Atom Q is more stable than the nucleus of Atom P.
