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.

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

Step-by-step explanation:

so, option a is wrong.

so,option b is wrong.

beta decay reaction for aluminum-28 is :

[where, 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.

this is not the answer this is just a question. is this middle school math?
