Question

When a Uranium 235 nucleus emits an alpha particle, which of the following is true about its daughter nucleus? Question 1 options:

The number of neutrons in the daughter nucleus is equal to those of parent nucleus

Neither the mass, charge, number of protons nor the number of neutrons of the daughter nucleus are the same as those of its parent.

The number of protons in the daughter nucleus is equal to those of parent nucleus

The charge of the daughter nucleus is equal to the parent nucleus

The mass of the daughter nucleus is equal to the parent nucleus

Explanation / Answer

U-235 ---> He + Th-231
92 2 (92-2) (number of proton)
235 4 (235-4) (number of neutron)
