Which of the following atoms has the same number of neutrons as 9Be?
xxMikexx [17]

Answer: -

¹⁰B

Explanation: -

For ⁹Be,

The atomic number is 4.

The Mass number is 9.

The number of neutrons = mass number - atomic number

= 9 - 4 = 5

For ⁹B,

The atomic number is 5.

The Mass number is 9.

The number of neutrons = mass number - atomic number

= 9-5 = 4

For ¹⁰B,

The atomic number is 5.

The Mass number is 10.

The number of neutrons = mass number - atomic number

= 10-5 = 5

For ¹⁰Be,

TThe atomic number is 4.

The Mass number is 10.

The number of neutrons = mass number - atomic number

= 10-4 = 6

For ¹²C,

The atomic number is 6.

The Mass number is 12.

The number of neutrons = mass number - atomic number

= 12-6 = 6

V = volume

t = time

In this problem I have volume and density as data.

There is no way to calculate the time so the correct answer is the "d" option
