Question

in beta decay the parent and daughter nuclei have the same number of _________​

Answer 1

Explanation:

they have the same number of electrons

Answer 2

The parent and daughter nuclei has the same number of mass of both remain same.

• In beta decay there are two types of beta decay one is the positive decay and second is negative decay.
• In the positive beta decay, the mass of the parent and daughter remain same but the atomic number increases by one.
• In the negative decay the mass of the parent and daughter remain same but the atomic  number decreases by one.
• So, there is only one quantity that changes is the atomic number and mass remain same.
