Types of radioactive decay

Question 1

Alpha Decay

Answer 1

forms a Helium ion. 4^2He

Question 2

Beta Decay

Answer 2

neutron converted into a proton and an electron ejected. 0^-1e

Question 3

Positron Emmission

Answer 3

Converts a proton to a neutron and a positron (a positive electron) 0^1e

Question 4

Electron Capture

Answer 4

proton to neutron and captures an e- from inner orbital add 0^-1e to reactants
turns solid to gas

Question 5

Gamma emmission

Answer 5

produces a nucleus that drops in energy state by releasing gamma radiation

Question 6

Spontaneous Fission

Answer 6

a heavy nucleus splits into a lighter nucleus with a release of energy

Question 7

number of nucleus at time t

Answer 7

Nt = N0 x (1/2)^n
