Phys Spring 2017 2s1 Name Daily Problem due Mon. Apr. 24 Show anyour work and Due at the beginning of class Fill in include units in your answers for credit. the missing products) in full Also where r the following nuclear decay reactions. Use the notation for indicate whether symbol, zisthe atomic number. and A is the atomic mass number. electron caprure. each reaction an example alpha decay, beta decay, beta decay. or is of 31 (a) Si 14 e i a, A ,P or EC? (b) 210 2He a, P-, or EC? P+, (c) i Na e- v a, P-, or EC?

Explanation / Answer

31Si14 ------- 31 SI14 +e + v

it is a decay

2.) 210 Pb 82 -------.> 206 Pb 80 + 4He4

it is alpha decay

3.) 22Na11 + e -------. 22Na11 +v

it is + decay

In beta minus () decay, a neutron is converted to a proton and the process creates an electron and an electron antineutrino; while in beta plus (+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. +decay is also known as positron emission
