Which of the following statements best describes the properties of aluminum-28?
a. Aluminum-28 has a higher percent abundance in nature than aluminum-27
b. Aluminum-28 has one more proton than aluminum-27.
c. When aluminum-28 undergoes beta-decay, magnesium-28 is produced.
d. When aluminum-28 undergoes beta decay, silicon-28 is produced.​

Answer:

d. When aluminum-28 undergoes beta decay, silicon-28 is produced.​

Step-by-step explanation:

  • aluminum-27 has an abundance percentage >99.9%. aluminum-28 will have less than that.

so, option a is wrong.

  • Aluminum-28 has one more neutron than aluminum-27.
  • Aluminum-28 will have 13 electrons, 13 electrons and 15 neutrons.
  • Aluminum-27 will have 13 electrons, 13 electrons and 14 neutrons.

so,option b is wrong.

beta decay reaction for aluminum-28 is :

[tex]Al_{13}28 -> Si_{14}28 + \beta _{-1} 0[/tex]

[where, [tex]A_{c}b[/tex] represents, element A,

b: its mass number[=number of protons+number of neutrons in the element]

, c : atomic number[=number of protons in the element]

so, option c is wrong and option d is correct.
