Answer 2

i think its d

Answer 3

beta particle is an electron, (not helium nucleus)
it will increase atomic number by 1


represented by \(\beta \)

Answer 4

so its b

Answer 5

penetration power of beta particle is more than alpha

mass number does not get affected by beta emision

Answer 6

o it is d

Answer 7

the overall mass number stays same!
so it is A :)

Answer 8

a
