What element is the product of dysprosium-166 (Dy) undergoing beta and gamma decay

Question

HELLLLP

anonymous · Answer

you can view it like this: beta decay = 2 protons and 2 Neutrons taken from the original atom, so the mass number of the product will be 166-4, while the proton number will (the proton no. of Dy)-2

anonymous · Answer

gamma decay is just energy so no protons or neutrons are left out.

alpha decay  is ejecting 2 protons and 2 neutrons, 
beta minus decay is  a neutron turning into a proton ejecting and electron (and electron antineutrino)

anonymous · Answer

sorry, lol mixed up the alpha and beta. thanks @UnkleRhaukus 
so the product is (the proton no. of Dy)+1 with the same mass number of 166

unklerhaukus · Answer

beta minus decay$$^A_ZN\to^A_{Z+1}N'+e^-+\bar\nu_e$$

unklerhaukus · Answer

$$^{166}_{66}\text {Dy}_{100}\quad\to\quad^{166}_{66+1}\text?+e^-+\bar\nu_e$$
