Question

An atom of germanium-69 emits a positron.
Express your answer as a nuclear equation.

Answer 1

69/32Ge --> 0/+1 e + 69/31 Ga

Answer 2

Answer:

The nuclear reaction is expressed as:

$_{32}^{69}\textrm{Ge}\rightarrow _{31}^{69}\textrm{Ga}+_{+1}^0e$

Explanation:

Positron decay is a process which a proton gets converted into neutron and an electron neutrino and releases positron particles. This particle carries a charge of +1 units.

$_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e$

An atom of germanium-69 emits a positron.

The nuclear reaction is expressed as:

$_{32}^{69}\textrm{Ge}\rightarrow _{31}^{69}\textrm{Ga}+_{+1}^0e$
