The chemical rehearsal is founded by the national association of university or education defines as mathematical.
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
C) 24
Explanation:
When a radioactive isotope of Vanadium, V decays by producing a beta particle and gamma rays, the atomic number will be 24.
Vanadium is the 23rd element on the periodic table.
It has a mass number of 51.
atomic number is 23
⁵¹₂₃V
A beta particle is symbolized as °₋₁B
Gamma rays are represented by Y
Now to the equation:
⁵¹₂₃V → ₐⁿK + °₋₁B + Y
In a nuclear reaction the mass an atomic number is conserved
51 = n + 0
n = 51
23 = a -1
a = 24
We can see that the nuclide formed will have an atomic number of 24
