What atom has the same number of neutrons as 9^B

answer:

¹⁰B has the same number of neutrons as ⁹Be

Explanation:

¹⁰B has the same number of neutrons as ⁹Be

Mass number of ⁹Be = 9

Atomic number of ⁹Be = 4

Number of neutrons of ⁹Be = mass number - atomic number

= 9 - 4 = 5

Mass number of ¹⁰B = 10

Atomic number of ¹⁰B= 5

Number of neutrons of ¹⁰B= mass number - atomic number

=10 - 5 = 5

i believe the answer is true.
