alpha
beta
gamma
electron
2. in the beta decay of bismuth-214, what daughter element is produced? (you may need to refer to the periodic table in the lesson.)
pic 1 is for question 1, and pic 2 is question 2.

1) Answer is: beta decay.

Nuclear reaction: ⁴⁰K → ⁴⁰Ca + e⁻ + νe (electron antineutrino).

Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.  

There are two types of beta decay: beta minus and beta plus.  

In beta minus decay, neutron is converted to a proton and an electron and an electron antineutrino.

In this nuclear reaction, potassium (atomic number 19) changes to calcium (atomic number 20), atomic number Z is increased by one.

2) Answer is: ²¹⁴₈₄ Po.

Nuclear reaction: ²¹⁴Bi→ ²¹⁴Po + e⁻ + νe (electron antineutrino).

This is also beta minus decay, neutron is converted to a proton and an electron and an electron antineutrino.

In this nuclear reaction, bizmuth (atomic number 83) changes to polonium (atomic number 84), atomic number Z is increased by one.
