When ( ^{53}_{26}Fe ) undergoes a single beta emission, which of the following is produced?

• ( ^{54}_{26}Fe )

• ( ^{53}_{25}Mn )

• ( ^{54}_{27}Co )

• ( ^{53}_{27}Co )

Answer explanation

When (^{53}_{26}Fe) undergoes beta emission, it transforms into (^{53}_{25}Mn), as the atomic number increases by 1 while the mass number remains the same.

The alpha decay of ( ^{238}_{92}U ) produces an atom with a mass number of...

• 234

• 236

• 238

• 240

Answer explanation

The alpha decay of uranium-238 (^{238}_{92}U) results in an atom with a mass number of 234, as the alpha particle has a mass number of 4 and the remaining atom has a mass number of 238-4=234.

The beta decay of ^{238}_{90}Th produces an atom with an atomic number of...

• 89

• 90

• 91

• 94

Answer explanation

In beta decay, a neutron is converted into a proton, increasing the atomic number by 1. Therefore, the atomic number of the product atom is 90 + 1 = 91.
