Question

What two quantities are always conserved in a nuclear reaction equation?

A atomic mass and atomic number
B the number of neutrons and protons
C atomic mass number
D number of neutrons​

Answer 1

I believe the awnser is A

Answer 2

Answer:B

Step-by-step explanation:

Option A:

In the nuclear reactions,neutron can be split into proton an electron.

In this case,the number of protons are increasing,increasing the atomic number.

Hence,the atomic number is not conserved.

Option B:

In any reaction the sum of number of neutrons and number of protons remain constant before and after the reaction.

Option C:

The mass number may change for the atoms.For example
`\alpha` emission reduces the atomic number by
`2.`

Option D:

In the nuclear reactions,neutron can be split into proton an electron.

So,they number of neutrons may change.
